Pressure-volume (PV) work done by an ideal gaseous system at constant volume is (where E is internal energy of the system)

A

`-Delta P//P`

B

zero

C

`-V Delta P`

D

`-Delta E`

Text Solution

Verified by Experts

The correct Answer is:
B

From 1st law of thermodynamic
`Delta E=q+w`. Now `w= P Delta V` for `Delta V= 0`
w= 0
