A gas can be ken from A to B via two different processes ACB and ADB. When path ACB is used 60 J of heat flows into the system and 30 J 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

80 J

B

100 J

C

20 J

D

40 J

Text Solution

Verified by Experts

The correct Answer is:
D
For ABC, `DeltaQ=DeltaU +DeltaW`
` 60 = DeltaU +30 gt DeltaU = 30J `
For ADC, `DeltaQ = DeltaU + DeltaW = 30 + 10 = 40J`
