Problem

A vintage steam locomotive whistle operates by releasing hot steam at temperature

T_1 = 400\;\text{K}

into the atmosphere at temperature

T_0 = 300\;\text{K}

. The whistle chamber has a volume of

V = 0.5\;\text{L}

and initially contains steam at pressure

P_1 = 3.0\;\text{atm}

. When the whistle valve opens, steam escapes and the remaining steam in the chamber quickly equilibrates to atmospheric temperature while maintaining constant volume. Assuming the steam behaves as an ideal gas, what is the final pressure of the steam remaining in the whistle chamber after thermal equilibration?
