Why does shaken soda explode? Does ice melt first in fresh or salt water?

This video features experiments that have been shown to me by science teachers over the years. Does ice melt fast in salt water or fresh water was an experiment introduced to me at the Utah Science Teachers' conference. The ring of metal over a chain demo came from a teachers event in Florida. The idea shaking a carbonated drink increases pressure came from an email.
Special thanks to Petr Lebedev for building the pressure gauge.

The closest supermarket from where I live is 500 meters (roughly) and it takes me 12 minutes to walk there and back at a walking speed of 5 kph (3 mph).

I was at a place where people were selling all kinds of puzzles and things and one that they were demonstrating was the ring and chain. The guy said he would give it to me for free if I could get it to stick on my first try. So instead of just going for it, I looked it over and thought for a second and pictured in my head what I needed to do to get it to stay. So I dropped it correctly and it stuck and the look of shock on the guys face was better than a free puzzle.

@rojirrim7298
@rojirrim7298 4 роки тому
@Daniel Kintigh Not about beating anybody :) just about letting people know. Since rapid cameras record high frame rates only to lower them at editing, they're effectively slowing time. Sound are air vibrations, and pitch is a sense of the frequency of those vibrations. By "slowing time" 10 times, all sounds reduce their frequency by a factor of 10, and so many audible noises would become infrasounds, and other high pitch sounds would become very low. Weird stuff, but it's cool to see how people came up with the idea of editing audio and make it sound Slo-Mo like

Similar to the ring latching on the chain, an inverse kind of trick is to pull off any elastic from a large number of them looped around the same stick. Pull on your chosen one away from the stick, then pull the loop over the top of the stick and you will liberate only your chosen elastic while leaving the others on the stick, (instead of having to pull off all the ones above it or something equally messy).

very interesting video but i have to say one thing about the carbonated drink normally (at least in austria) if you buy a bottle with a carbonated drink in it and you shake it, the bottle will be harder to compress, which means that the pressure increases however we all know that it doesnt get harder to compress anymore after a sometime of shaking or just standing somewhere so if you ask if the pressure will increase, the answer to this question can be different, based on some variables

No. 3 is depending on length and weight of the chain, distance between the chain strands and also on weight and rotation speed of the ring. The more you increase the length of the chain, increase the weight of the chain, reduce the distance between the chain strands, reduce the weight of the ring or decrease the rotation speed of the ring the more unlikely it becomes to achieve the same result. It's like the phenomenon of a buttered toast falling from the table mostly landing on the buttered side.

Try thinking of it in it's reverse. If you take the chain (which is a enclosed loop) and thread it through the ring so you have two equal lenghts of chain with the ring hanging in the middle, you then take one of the sides of the chain and loop it through the other side of your chain. As long as you pull on the side that you looped through your chain, the knot will stay tightened. 4:15 is the same thing but with the ring going through the chain and it's just a bit flashier because instead of you doing the loop by hand, gravity, inertia and the geometry of the ring is doing all the work for you.

@zonedout6432
@zonedout6432 4 роки тому
It's more of a chemistry thing then a physics one. Chemical equilibrium is probably something he could do an entire video on. Basically when you first seal a bottle of soda there's some CO2 dissolved in the liquid soda but not a lot in the air above the soda. CO2 wants to be a gas at room temperature though so some CO2 molecules separate from the soda and go into the air above the soda which increases the pressure in the bottle until the air above the soda can't take anymore CO2 which means theres a maximum pressure that can exist in the bottle from CO2 ( this process takes a long time under normal conditions though). When the pressure is at its max we say the CO2 is at equilibrium because the pressure stops changing. It turns out that there's a ratio for this process so there will always be x molecules of CO2 in the air for y molecules of CO2 dissolved in liquid and that ratio doesn't change unless you change the temperature of the bottle which shaking doesn't do. The reason soda sprays out of the bottle when you shake it is because the CO2 that would have escaped anyway in an unshaken bottle is mixed into the soda more (in the fizz) so the CO2 molecules hold the soda and take it out of the bottle with them. The other reason is that when you open the bottle the pressure drops so ratio of CO2 in air vs liquid is no longer in equilibrium and the CO2 will want to go into the air to try to reestablish the previous equilibrium. This happens slowly in an unshaken bottle (or cup) but super quickly in a shaken one because the air bubbles along the sides of the bottle help the CO2 separate from the liquid much faster. I hope this makes more sense

@nggdowt 4 роки тому
It was kind of a trick question. If you open a bottle and release the gas, then immediately cap it with his pressure gauge, it'll says "low". If you then shakes the bottle, the pressure will immediately jumps to "high", just like a lot of people expects. The trick he did in the video, is that he didn't immediately shakes the bottle, but instead let it rest so then the CO2 slowly releases from the coke. That way the pressure gauge will already starts at "high" before he shakes the bottle, creating an illusion that pressure doesn't change even after shaking.
@reteip9

I am now coming back to this video 6 months after originally watching it because I bought an ice cream today & had it in my car & as I was about to turn the cold AC on the ice cream I remembered this video & how the cold actually speeds up melting so I left the AC off & ended up with no mess in my car, thanks Derek!
