In a closed insulated container, a liquid is stirred with a paddle to increase the temperature. Which of the following is true?

A

`DeltaU = w ne 0, q = 0`

B

`DeltaU = w = q ne 0`

C

`DeltaU = 0, w = q ne 0`

D

`w = 0, DeltaU = q ne 0`

Text Solution

Verified by Experts

The correct Answer is:
A
(a) Since container is closed and insulated, te process is adiabatic so that q == 0
`DeltaU = q + w`
`DeltaU = w ne 0`
