A gas undergoes change from state A to state B. In this process, the heat absorbed and work done by the gas is 5 J and 8 J, respectively. Now gas is brought back to A by another process during, which 3 J of heat is evolved. In this reverse process of B to A :
Text Solution
Verified by ExpertsThe correct answer is:
C
A 
B :
q = +5 ; W = –8 ∴ Δ E = –3
B 
A :
Δ E = 3 ; q = –3 ∴ W = +6J
⇒ 6J of the work will be done by the surrounding on gas.
