Question:medium

At constant pressure, equal amounts of heat are supplied to a monatomic gas and a diatomic gas separately. The ratio of the increases in internal energies of the two gases is

Show Hint

The change in internal energy $\Delta U$ always depends on $C_v$ ($\Delta U = nC_v\Delta T$), regardless of the process. The heat supplied $Q$ depends on the process ($Q=nC_p\Delta T$ for isobaric). The ratio $\Delta U / Q_p = C_v/C_p = 1/\gamma$.
