The molar heat capacity C for an ideal gas going through a given process is given by C=a/T, where a is a constant, and T is the temperature. If γ=CP/CV, the work done by one mole of gas during heating from Tο to η Tο through the given process will be
A.T/a lnη
B. alnη−(η−1/γ−1)RTο
C. aln η−(γ−1)RTο
D. None of the above
