Passage / Comprehension
An ideal gas with the adiabatic exponent γ undergoes a process in which its internal energy relates to the volume as U = k·Vm, where k and m are constants.
What is the molar heat capacity of the gas in this process?
Options:
Answer:
A
Solution:
C = dQ/dT = Cv + dW/dT. dW = ((γ−1)/m) dU = ((γ−1)/m) Cv dT = (R/m) dT. Hence C = R/(γ−1) + R/m. Matches (a).
