Nitrogen dry ice
WebPound for pound, dry ice has almost twice the cooling power of liquid nitrogen, because it takes a lot of energy to turn CO 2 directly from a solid into a gas (136.5 calories per gram), whereas liquid nitrogen needs only a measly 47.5 calories per gram to vaporize. WebSo, dry ice and liquid nitrogen are similar, but made of completely different elements. Using dry ice to make ice cream is going to take a little more manpower and time, and liquid …
