The first law of thermodynamics for isothermal process is

A

`q = - W`

B

`DeltaU = W`

C

`DeltaU = q_(v)`

D

`DeltaU = - q_(v)`

Text Solution

Verified by Experts

The correct Answer is:
A
According to first law of thermodynamics,
`DeltaU = q+W`
where, `DeltaU =` internal energy
` q =` Heat, w = Work done
For isothermal process , `DeltaT = 0 , DeltaU = 0`
`:. q = - W`
