Chapter 15, Problem 7P

(a)

To determine

The variation in internal energy of a gas that undergoes a cyclic process in a closed container from state 1 to state 2 and back to state 1.

(b)

To determine

The magnitude of the work that is done by the environment upon the gas on $P\text{-}$ verses $\text{-}V$ graph from both state 1 to state 2 and state 2 to state 1.

(c)

To determine

Ift he total work done on the gas is positive, negative or zero in the whole process from state 1 to state 2 and from state 2 to state 1.

(d)

To determine

The heating process of the gas from state 1 to state 2 and then from state 2 to state 1 and also throughout process from state 1 to state 2 and then back to state 1. Also determine whether the total heat transfer of the gas is positive, negative or zero in nature.
