Compressed air coming out from a punctured
football ________.
becomes hotter
becomes cooler
Remains at the same temperature
May become hotter or cooler depending upon the
humidity of the surrounding air
becomes cooler
Compressed air coming out of punctured
football becomes cooler because of adiabatic expansion. Adiabatic
expansion causes a drop in temperature of the molecules present in the gas or
air. Also, a lot of pressure is lost during this type of expansion. This is
related to the principle of thermodynamics.
Hence, the correct option is (B).
