Heat and Thermal ExpansionHard
Question
A gas takes part in two processes in which it is heated from the same initial state 1 to the same 1 to the same final temperature. The processes are shown on the P-V diagram by the straight line 1 - 2 and 1 - 3.2 and 3 are the points on the same isothermal curve. Q1 and Q2 are the heat transfer along the two processes. Then :-
Options
A. Q1 = Q2
B. Q1 < Q2
C. Q1 > Q2
D.insufficient data
Solution
Work done in process 1 - 3 is greater than that in process 1 - 2. while change in internal energy is same for both processes ∴ Q1 > Q2
