For one complete cycle of a thermodynamic process gas as shown in the P-V diagram, which of following correct?

A

`Delta E_("int")=0, Q lt 0`

B

`Delta E_("int")=0, Q gt 0`

C

`Delta E_("int") gt 0, Q lt 0`

D

`Delta E_("int") lt 0, Q gt 0`

Text Solution

Verified by Experts

The correct Answer is:
A
For cyclic process `Delta U=0 implies Delta E_("int")=0` and `Delta Q= Delta W lt 0` (because direction is anticlockwise).
