Problem

A gas is compressed from a volume of

2\text{m}^3

to a volume of

1\text{m}^3

at a constant pressure of

100 \text{ N/m}^2

. Then it is heated at constant volume by supplying 150 J of energy. As a result, the internal energy of the gas: a. increases by 250 J b. decreases by 250 J c. increases by 50 J d. decreases by 50 J
