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 amount of heat is to be transferred to this gas to increase its internal energy by ΔU?
Options:
Answer:
B
Solution:
First law: Q = ΔU + W. From the work relation W = ΔU(γ−1)/m, Q = ΔU(1 + (γ−1)/m). Traps: (c) subtracts the work as if the gas were being compressed while its internal energy rises; (a) inverts the (γ−1)/m factor; (d) adds a spurious R that breaks dimensional consistency. Matches (b).
