B

A thermodynamic property which is intensive is additive.

C

Work done may be zero in a cyclic process.

D

For a simple compressible substance, the relation dq - P . Dv = 0 is true for any cycle involving mechanical work only.

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
Work is a form of energy exchange between system and surrounding in adiabatic process.
Intensive property is not additive. In cyclic process work may be zero. For cyclic process
`dU=0=dq+dwimpliesdq-Pdv=0`
