Air in a can?

Question

since i got it today i've noticed how cold it gets quickly.

it started developing alot of frost on the can but now i know that i'm supposed to use short sprays instead of long ones XD

anyways i was wondering do all 'air in a can' products have the same amount of air?

2nd, is it possible to freeze water by using 'air in a can'?

thanks.

Answer 1

Boyle's law says that when you reduce the pressure on a gas, you reduce its temperature.

Canned air is sold by weight, so cans with the same weight will have the same amount. Cans come in different sizes, of course, so they will not all be the same.

Sure it's possible to freeze water by spraying canned air. The frost you get on the can is water (humidity in the air) frozen.
