Chemistry - Thermodynamics - I Question with Solution | TestHub

(a) A perfect gas has the energy of a classical ideal gas, C_v,m = constant by equipartition, so it does not vary with T: true. (b) Work can still cross the boundary, so the system is only closed and adiabatic, not isolated: false. (c) U, H, G, S are all state functions, so their cyclic integral is zero: true. (d) Equal end temperatures do not make the process isothermal (T may vary in between): false. Ans: (a), (c).
