Question

A gas can be taken from A to B via two different processes

A C B

and

A D B

. When path

A C B

is used 60 J of heat flows into the system and 30J of work is done by the system. If path ADB is used work done by the system is 10 J. The heat Flow into the system in path ADB is : A gas can be taken from A to B via two different processes A C B and A D B . When path A C B is used 60 J of heat flows

A gas can be taken from A to B via two different processes A C B and A D B . When path A C B is used 60 J of heat flows

Correct answer: A. 40 J

U remains same for both paths ACB and ADB Δ Q_ A C B =Δ W_ A C B +Δ U_ A C B 60 J=30 J+Δ U_ ACB U_ ACB =30 J As change in internal energy depends only on initial and final point Δ U_ ADB =Δ U_ ACB =30 JΔ Q_ ADB =Δ U_ ADB +Δ W_ ADB =10 J+30 J=40 J
