No. To figure this out, one has to look beyond the kinetic theory. A hot metal cools down by losing translational kinetic energy to neighbouring objects, but that's not the only way. Excited atoms of the heated body radiate energy in form of discrete masless packets called photons. As excited atoms emit photons, they lose energy and (slowly) cool down. For the record, that's how Sun's radiation reaches the Earth, and the way Microwave ovens work.

@BrettHar1234 роки тому
Entropy and energy are two distinct concepts. Energy is conserved, but entropy refers to the ability of the energy to do useful work. The universe began with an extremely low entropy, which is the reason the early universe was so simple. What makes it so confusing is that on Earth entropy does not increase, it has been decreasing since it was formed over 4 billion years ago. This doesn't violate the second law, it's just that we continually receive high energy, low entropy photons from the sun every day, which are used by plants to photosynthesise, creating a store of low entropy for the entire biosphere. At night, the waste heat from every biological, geolological and atmospheric process is radiated out to space, in the form of high entropy infra-red radiation, far more than what we received from the sun. What remains is the order and complexity of the biosphere, and now increasingly the highly ordered creations of human beings, everything from your favourite movie to the General Theory of Relativity, are all highly complex evolved systems, but nothing would exist if not for the basic entropy deficit, driven straight from the nuclear fusion in the Sun's core. The overall entropy of the universe is increasing, but not everywhere, especially on chemically favourable rocks, at a favourable distance from a stable star.

@lucaspierce33287 років тому
Ask yourself this if all energy is conserved, then how would things decay into nothing if you can destroy it or create it from nothing and if entropy is to increase then how can there be a maximum. Another thing is all particles are entangled 'already' sense the big bang that's the essence of superposition, they are seemingly different expression of the same thing the underlying oneness of all things. The zeroth law doesn't allow temperature to reach zero point without increasing surrounding entropy flux at a boundary limit of the ZPE field, but as it interacts with its environment it to goes to non-zero. So as things cool down they must heat up as they can never be truly closed from a environment. Partonic sub-quantum pixelation of granulification dynamics allows a bidirectional transfer of heat/motion/energy within an entangled fractalized reality. Sustaining ZPE for long durations could produce energy thats proportional to it's (boundary size × time) × (plank mass × speed of light squared) or something like that!?...

@mikebellamy7 років тому
The best recommendation I can give is Wark 'Thermodynamics' but ONLY the original 1966 1st edition. Do not use the latest edition because it will not help you. It omits the derivation of the Clausius equation from the Boltzmann equation in order to tow the line of the current paradigm (universe made itself in spite of 2nd law which is wrong). You are wrong because you do not understand what Ludwig Boltzmann's equation means. You must understand no object above absolute zero temperature is "at rest". Increasing disorder is the tendency for systems to move toward equilibrium. Equilibrium is the state where both the momentum and position of atoms is evenly distributed which may be summed up as the most probable state or state of maximum disorder. NOTE: It is not correct (as the paradigm asserts) to say entropy increase is completely specified by the dispersion of energy (momentum of atoms).. it must encompass BOTH momentum AND position. This is why there is so much confusion.. Entropy is NOT measured completely in terms of energy dispersion alone. Probability is the key measure which Boltzmann discovered and precisely what is equation reveals.

Can someone explain this to me... if entropy always increases... Let's say I have a giant box in the universe, nothing outside can influence it, and I load the box with either A) wispy hydrogen; or, B) iron dust, and we wait. Box A will create a star after gravity gathers the hydrogen, and box B will take the random, disordered iron particles, and great a sphere of solid iron, possibly a neutron star if there's enough of it. I cannot see how either result is MORE disordered than the random hydrogen, or the iron dust.
@Hypatia42427 років тому
I think the answer is once compacted into a star or ball, there is no future in which, given the current physical laws of the universe, it can do anything else. It has reached it's final state. There is neither a heat based or new order based arrangement it can achieve. It's been a long time since I had physics, so we might need an experimenter to comment too :)
@kurtbjorn7 років тому
Hypatia4242 Thanks! I think you are correct. I've thought about it a bit after posting... here's my lame theory. For the iron, each particle has potential (height) energy relative to the future center of mass. As each particle falls into the ball, it loses energy, liberates heat. Eventually the ball of molten iron cools into an isothermal mass, thus the energy of the system goes from high (potential) to low (heat distributed via IR and other radiation). So if we think of it as an energy system, that might work. Same deal with the hydrogen. It has nuclear binding energy. It collapses into a star, is fused towards iron, energy radiates away. Eventually, the star cools into a brown dwarf or whatever; again, the energy of a system is reduced, leaving the cinders behind with no ability to do much of anything.

I just don't see how gravity fits into the "order to disorder" thought pattern. I still think the Big Crunch is a viable theory ... our obeservation is that the expansion of the Universe is expanding but it's just our observation. We don't understand our observations quite yet, do we? What if the red-shifting of galaxies and stars is due to an energy absorption effect of Dark Matter? Or what if Dark Energy is the Universe's battery, storing entropy until the Universe is so dispersed that gravity will overcome it?
@JasonJason2107 років тому
Interesting points, especially your first one. Also, I would add that dark matter has some effect on red-shifting...since gravity can interact with light. However, the influence is too small to explain what we observe. But we should be careful. While it's fun to speculate, if we choose not to go along with the mainstream scientific view, or at least a recognised challenge to it, then we are at best guilty of crack-pottery; and at worse, guilty of religious belief. One thing scientists do consider is the possibility that our understanding of gravity may be incomplete. They openly admit this when trying to explain dark energy.

Hot will ALWAYS flow to cold because true isolationism is non-existant. EVERYTHING that radiates thermal energy is connected at all times, to at least 1 external body. This is what drives the natural process through the whole universe toward equalibrium; aka maximum Entropy. Once the universe reaches maximum Entropy, potential becomes non-existant. The derivative of Entropy (S) divided by the derivative of time (t) is greater than, or equal to zero. Its the 2nd Law of Thermodynamics. Its the reason why manufacturer's of machines, air conditioning units for example, must always struggle to make higher efficiency units. Its also the reason why you must repeatedly vacuum clean your carpet, to strive to maintain a clean house. Entropy. The Arrow of Time. Or as in statistical Thermodynamics, its Hidden Information. Listen to Leonard Susskind. He is remarkable on the subject of Entropy as Hidden Information!
@postholedigger87267 років тому
Dr Al-Khalili, If a glass is dropped on a hard surface and breaks into pieces, why is that disorder? What else is the glass supposed to do? If the glass was supposed to break when it hit the hard surface, but instead bounced to the moon; that would be disorder. It seems to me that the action and position of each piece of broken glass could, in theory, be understood as an addition of force vectors defining action and reaction acting upon the glass and the hard surface. If a bomb or a star explodes it is because the forces containing the explosion were overwhelmed by the pressure from the explosion. If the explosion occurred and the star was supposed to fly apart, but didn't; that would be disorder. david
@mikebellamy7 років тому
Totally incorrect.. Boltzmann showed what order means.. Its simple, mathematical and quantifiable.. An ordered state = an improbable state..! The glass is improbable because there are vastly many more other arrangements for those atoms of silica than in the form of a glass..
@postholedigger87267 років тому
Mike Bellamy, Every single arrangement of "atoms of silica" is, in fact, vastly different from every other arrangement. of "atoms of silica" and is therefore in an improbable state. The glass is just one arrangement that is recognizable to the observer. Or put another way, one unique arrangement among many arrangements. Calling some arrangements order and other arrangements disorder is a philosophical opinion; not a natural law. The commonality of all of the silica arrangements is that they are the result of physical and chemical laws that brought them to their final form. This is true regardless of their particular physical condition at the time of observation. david
@mikebellamy7 років тому
Boltzmann's equation is NOT PHILOSOPHICAL.. You are only revealing colossal ignorance of the subject. The silica in the FORM of a wine glass is a MACROSTATE (produced=ordered by a specific mold). Whilst it does have a large number of microstates being different silica molecular arrangements possible from that same mold these are very much less than the possible arrangements without the mold. Which is WHY any specific wineglass is uncommon in the universe ie improbable = low entropy.
@postholedigger87267 років тому
Mike Bellamy, A man made mold simply provides another set of forces that form the silica into a particular shape. As the shape is magnified it becomes apparent that even these molded forms are vastly different from each other and are unique. In fact, if something is magnified to a high enough power, it is virtually impossible to tell if the object was made from natural or artificial processes. When looked at from this perspective, each wine glass is unique and therefore uncommon not only to every other wine glass, but also every other combination of silica atoms. The final form of anything, including the entire universe, is still the result of the forces that brought it to that state. A glass dropped on a hard surface and broken into pieces is also the result of the forces that brought it to that state. The fact that one form is useful or familiar and the other is not is an emotional opinion. Calling a star functioning similar to our sun "order" and a star exploding as "disorder" is a value judgement and has nothing to do with what is happening to the star. The actual state of an object has nothing to do with an opinion formed by an observer. What actually would be extremely improbable would be if there were two forms that were exactly alike on every possible level of observation. If that happened it would truly indicate a state of disorder due to the improbability of such an occurrence. Since each form of anything is unique, at some level of observation, If certain particular forms are viewed as a state of order and other forms viewed as a state of disorder, then that is a value judgement; which is an emotion. david
@2010COBHC6 років тому
the order-disorder thing is an often misunderstood point of entropy and thermo, mostly because it's not the complete story. To truly grasp entropy you need statistical mechanics. The fundamental assumption of statistical mechanics says that any microstate is equally probable to any other. To specify a microstate is to specify the position and momentum of every single particle in your system. In macroscopic systems, you see the issue: there's just too many to count, and you can't hope to measure the position and momentum of every single particle. The way around it is to try to figure out how many microstates are in each macrostate. A macrostate is specified when the temperature, pressure, volume, and particle number are specified. But a single macrostate can be achieved by many different microstates. Thus the most likely macrostate is the one that corresponds to the most number of microstates (recall the fundamental assumption). therefore the reason the glass is of higher entropy when broken is because there are more ways to arrange broken glass than fixed glass. You're correct to suspect that you could know more by treating force vectors on each individual atom in the glass, but since that's beyond our knowability, we treat the situation statistically. Stat mech is the best we can do under our ignorance (but it's worth noting that the ignorance is much more fundamental if you delve into the quantum statistical mechanics, since position and momentum are fundamentally unknowable to a particular degree). Hope this clears things up. I recognize your comment is months old but hopefully this provides more info.

@BrettHar1234 роки тому
On the contrary, intelligence is the effect of a continual entropy deficit, which has been lowering the entropy of Earth, at a more or less constant rate, for over 4 billion years. It drove the first life, evolution, and finally lead to a highly intelligent species, which is now the greatest creator of information on the planet. How it happened is complex, but the basis point is that solar photons have high energy and low entropy, which means it can do work, transform one state to another, plants photosynthesise storing the low entropy for animals to eat and continue to reproduce. At night, the waste heat, is radiated to the cold of space, keeping the Earth's temperature constant, but far more entropy is radiated to space, than what came from the sun. What are fossil fuels but an ancient store of very low entropy fuel, which means they can be used to create many different products. Look up non-equilibrium thermodynamic systems, life was inevitable once the initial conditions were in the right zone.
