Problem

75 J of thermal energy is transferred to an ideal monatomic gas at a constant pressure of

1.0 \times 10^5

Pa. The volume of the gas increases from

2.7 \times 10^{-3}\ \text{m}^3

3.0 \times 10^{-3}\ \text{m}^3

. What is the change in the internal energy of the gas? A. 45 J B. 105 J C.

-45\ \text{J}

-105\ \text{J}
