ChemistryEasysingle choice
Work done by a sample of an ideal gas in a process A is double the work done in another process B. The temperature rises through the same amount in the two processes. If CA and CB are the molar heat capacities for the two processes, then
Options:
Answer:
B
Solution:
Δ U is the same in both (same Δ T). q = Δ U + W, so nCΔ T = nCvΔ T + W and C = Cv + W/(nΔ T). With WA = 2WB (both positive, expansion work) and the same Δ T > 0, CA > CB. Matches (b).
