Thermodynamics — UPSC CSE 2022 Physics PYQ

A compressor designed to compress air is used instead to compress helium. It is found that the compressor overheats. Explain this effect, assuming that the compression is approximately adiabatic and the starting pressure is same for both the gases. \left[\gamma_{\mathrm{He}}=\frac{5}{3},\gamma_{\mathrm{Air}}=\frac{7}{5}\right]
