Question

an ideal gas of monoatomic molecules expands from its initial state A to a state B through an isobaric process and then further expands to a volume C . Find the work done by the gas ,increase in internal energy, and the energy transferred by heat to the gas over the whole process?

Answer 1

$$A_{AB}=-\frac{3}{2}\nu RT_{AB}$$

$$A_{BC}=\nu RT_{BC}$$
