Ideal gas is taken through the process shown in the figure :

A

In process `AB`, work doen by system in positive

B

In process `AB`, heat is rejected out of the system.

C

In process `AB`, internal energy increases

D

In process `AB` internal energy decreases and in process `BC` internal energy increases.

Text Solution

Verified by Experts

The correct Answer is:
B
In process `AB`
`T =` constant
`P =` increases `P alpha(1)/(V)`
or `V =` decreases `DeltaQ = DeltaW. Deltaw =- ve`
or `DeltaQ =- ve`
`:.` heat is rejected out of the system.
