Question 74: Thermodynamics & KTG

Question

From the following p-V diagram, an ideal gas undergoing a change of state from A to B. Four different processes I, II, III and IV as shown in the figure may lead to same change of state.

Accepted Answer

As work done = area under p-V curve, work done is maximum in case I.
Change in internal energy is independent of the path from A to B. Therefore, in all cases change in internal energy is same.

Answer

work done is maximum in case I

Answer

Change in internal energy is same in all  the four cases

Answer

Change in internal energy is same in IV and III cases, but not in I and II cases

Answer

Work done is minimum in Case II

Thermodynamics & KTG
