If you have a sore muscle, you get this pack and you sort of smash it. It becomes cold. Usually, how those things work is you're breaking the two pouches and allowing for the two things to mix. It's usually a salt that will dissolve in water that's going to drop the temperature down, and that's what they do when you make ice cream. That's why they use salt.
Yes, that's correct. Well, I think there's a different reason, really. Yeah, I'm an ice cream guy, okay? From way back. All right, I should weigh 100 lb more, but I exercise just to wear off the ice cream. So I would claim that salt and water does not lower the temperature.
False. Freezing point depression. It will go down. Delta T is equal to negative I K F times the molality. Mic drop. By how much will it go down? If you put salt in water, it goes down by 1.86 degrees C.
Will this work for table salt? Absolutely, yes. Because when you put sodium chloride in water, it's going to break apart into the ions. I'm doing an experiment tonight. Do it. You will feel it in your hand. I'm doing that experiment. That is cool, man. Tonight, I love it. The experiment gauntlet has been thrown down.
