1) n moles of an ideal gas undergoes a process A and B shown in the figure. The maximum temperature of the gas during the process will be A) 94p0V0nR B) 32p0V0nR C) 92p0V0nR D) 9p0V0nR Answer: Option AExplanation:p-V equation for path AB p=−(p0V0)V+3p0 ⇒pV=3p0V−p0V0V2 OR T=pVnR=1nR(3p0V−p0V0V2) For maximum temperature dTdV=0 ⇒3p0−2p0VV0=0⇒V=32V0 and p=3p0−p0V0=3p02 Therefore, at these values, Tmax=(3p02)(3V02)nR=9p0V04nR
