An adiabatic system can exchange energy with its surroundings.
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`
