Questions
One mole of an ideal diatomic gas undergoes a transition from A to B along a path A B as shown in the figure,
The change in internal energy of the gas during the transition is
detailed solution
Correct option is D
We know, ΔU=nCvΔT=n5R2TB-TA for diatomic gas, Cv=5R2=5nR2PBVBnR-PAVAnR [∵PV=nRT]=52PBVB-PAVA=522×103×6-5×103×4=52-8×103=-20 kJTalk to our academic expert!
