Four liters (0.004 m3) of liquid H2O at 32 oC (mass A) and one liter (0.001 m3)

Question

Four liters (0.004 m3) of liquid H2O at 32 oC (mass A) and one liter (0.001 m3) of solid H2O ice at -32 oC

(mass B) are sealed in a flexible, perfectly insulated container. The ice is wrapped in plastic so the masses do

not mix. Find the final temperature (oC), volume (m3) and total work (kJ) of the H2O after sufficient time

elapses for thermal equilibrium to be achieved. The mass and energy of the container and plastic wrap are

negligible. The internal pressure is constant at local atm. pressure of 100 kPa. The flexible container allows

expansion & contraction so work is not equal to zero (but it will be a small amount). NOTE: Moderate

pressure (<100 bar) has little effect on liquids and solids so the properties of saturated solid and saturated

liquid at the appropriate temperature are valid for any moderate pressure above the saturation pressure.
