Passage / Comprehension
An ideal gas with the adiabatic exponent γ undergoes a process in which its internal energy relates to the volume as U = a·Vα, where a and α are constants.
What is the molar heat capacity of the gas in this process?
Options:
Answer:
C
Solution:
Per mole, C = dQ/dT = dU/dT + dW/dT. dU/dT = Cv = R/(γ−1). From Q17, dW = ((γ−1)/α) dU, so dW/dT = ((γ−1)/α)·Cv = R/α. Hence C = R/(γ−1) + R/α. Matches (c).
