Thermodynamic Processes

A gas undergoes a change in which its pressure ' P ' and volume ' V ' are related as $PV^{n} =$ constant, where n is a constant. If the specific heat of the gas in this change is zero, then the value of $n$ is ( $\gamma =$ adiabatic ratio)

Show answer and solution

Answer: (d)

Specific heat zero means $Q = 0$ for any temperature change, i.e. the process is adiabatic.
Adiabatic process: $PV^{\gamma} =$ constant, so $n = \gamma$ .
So the answer is (d).
