Q. An ideal gas expands in such a manner that its pressure and volume can be related by equation $PV^{2} =$ constant. During this process, the gas is
A) Heated
B) Cooled
C) Neither heated nor cooled
D) First heated and then cooled
Explanation
(b) $PV^{2} =$ constant represents adiabatic equation. So during the expansion of ideal gas internal energy of gas decreases and temperature falls
