Passage / Comprehension
An ideal gas (CP/Cv = γ) is expanded so that the amount of heat transferred to the gas is equal to the decrease in its internal energy.
What is the relation between T and V of gas in this process?
Options:
Answer:
C
Solution:
First law: dq = dU + P dV with dq = -dU gives -2nCv,m dT = P dV = nRT dV/V. With Cv,m = R/(γ-1): (dT)/T = -(γ-1)/2(dV)/V. Integrating, T V(γ-1)/2 = constant. Matches (c).
