Physics - Heat & Thermo Question with Solution | TestHub

When an ideal gas undergoes an adiabatic change causing a temperature change $\Delta T$: (i) there is no heat gained or lost by the gas; (ii) the work done on the system is equal to the loss in internal energy; (iii) the change in internal energy per mole of the gas is $C_v\Delta T$, where $C_v$ is the molar heat capacity at constant volume.
