Mathematical equation of first law of thermodynamics for isochoric process is

A

`DeltaU = q_(v)`

B

`-DeltaU = q_(v)`

C

`q=-W`

D

`DeltaU =W`

Text Solution

Verified by Experts

The correct Answer is:
A
`DeltaU =q,` is the mathematical equation of first law of thermodynamics for isochoric process. Because for isochoric process,
`DeltaV=0 therefore W = PDeltaV=0 therefore DeltaU=q_(v)`
