Question

An ideal gas expands at a constant 5.0 atm from 200 mL to 500 mL. Heat then flows out at constant volume until the temperature returns to its original value. Find the total work done by the gas in joules (one decimal). What is the net heat flow into the gas?

Only the isobaric step does work: W = P Δ V = 5 × 1.013 × 1 0 5 × 300 × 1 0 − 6 = 151.9 J. The temperature is unchanged, so Δ U = 0 and the net heat into the gas is 151.9 J.
