A sample of liquid in a thermally insulated container is stirred for 1hr by a mechanical attachment to a motor in the surroundings, which of the following thermodynamic quantity for the system is zero

A

Work (W)

B

Change in internal energy `(DeltaE)`

C

Change in enthalpy `(Delta H)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
D
For a thermally insulated container, `Delta q = 0` But work (W), change in internal energy `(Delta E)` and change in enthalpy `(Delta H)` are non zero.
