Do ideal gases absorb heat when they expand?
Answer:
As a gas is heated, the molecules move faster and take up more space, or expand.
There is a process where gases expand rapidly and the temperature goes down.
each gass absorbs heet when it expands and it is called as joulthomson effect. that gass is ideal which absorbs heet equvalent to its area of expanssion. greater is the expantion greater will be the heet absorbtion.
they don't absorb energy, the molecules just have more room to move around so they gain more energy and therefore heat up.
yes if heat/energy is available to adsorb (which it generally is). This is how air conditioning works. You have a high pressure liquid, expanding into a lower pressure gas. Heat is adsorbed. High pressure vapor to lower pressure does the same thing but is more inefficient than what is used in refrigeration
