A rigid vessel of volume 0.400 m3 containing H2 at 21.25ºC and a pressure of 715 x 103 Pa is connected to a second rigid vessel of volume 0.750 m3 containing Ar at 30.15ºC at a pressure of 203 x 103 Pa. A valve separating the two vessels is opened and both are cooled to a temperature of 12.2ºC. What is the final pressure in the vessels? Vof H2 := 0.400 m3 PH2 := 715*10^3 Pa V of Ar := 0.750 m3 P of Ar := 203*10^3 Pa
