expansion cooling & warming?
Answers
Adiabatic heating and cooling. The adiabatic compression of a gas causes a rise in temperature of the gas. Adiabatic expansion against pressure, or a spring, causes a drop in temperature. In contrast, free expansion is an isothermal process for an ideal gas.
plss follow me...
ANSWER:-
It's called adiabatic cooling and heating and occurs because of change in the air pressure here's ........ Pressure decreases with altitude the air parcel expands . Expansion causes air to cool when the airs cool to it's so called condenses and becomes visible.....

Question:-
Why does an expanding gas cool?
Answer:-
Heat can be seen as the total amount of energy of all the molecules in a certain gas ..... Therefore the sometime use expanding gas to cool the infared cameras. When gas expands, the decrease in pressure causes the molecules to slow down . This makes the gas cold.
