The box “Thermodynamics Dramatized” shows the crushing of an inverted steam-filled can placed in a pan of water. Would the water need to be cold? Would crushing occur if the water were hot but not boiling? Would it crush in boiling water? (Try it and see!)
Solution 19E If the water is hot, but not boiling, crushing should still occur as the hot water will have a temperature lower than the steam. The steam will release its energy and thus there will be condensation. This condensation will lead to a very low pressure and then the can will be crushed by the atmospheric pressure. When the water is boiling, it will have the same temperature as the steam. So, the steam will not lose any heat and the pressure inside the can should remain the same. There should be no crushing of the can.
