The pressure falls more rapidly in a quasi-static, adiabatic process than along an isotherm when the volume of the gas is increased.

Question

Quizplus · Accepted Answer

In a quasi-static, adiabatic process, the pressure and volume of the gas change slowly and without any heat transfer. This leads to a decrease in pressure when the volume is increased, and the rate of decrease is more rapid than that along an isotherm where the temperature is constant. This is because in an adiabatic process, there is no exchange of heat energy to maintain a constant temperature, therefore, a change in volume leads to a change in pressure more quickly.
