Question

An ideal monoatomic gas is taken from state a to b , then from b to c and finally back to state a as shown ​

Answer 1

Explanation:

Internal energy of a gas

U=

2

3

nRT

Where, R is constant.

Thus, for a given number of moles of the same gas

U∝T

From the graphs, we conclude that

U
