A sample of liquid in a thermally insulated container is stirred for 1 – InterviewSolution

1.	A sample of liquid in a thermally insulated container is stirred for 1 hr by a mechanical attachment to a motor in the surroundings, which of the following thermodynamic quantity for the system is zero
Answer» Work (W) Change in internal energy `(DeltaE)` Change in enthalpy `(DELTAH)` None of these Solution :For a thermally INSULATED container, `Deltaq=0` But work (W), change in internal energy `(DeltaE)` and change in enthalpy `(DeltaH)` are NON zero.
