4. The equation of state for a van der Waal's gas is: RT Vm-b p= a V² m 2 where Vm is the molar volume, V/n. Starting with an expression for U(S,Vm), derive an expression for the internal pressure, îò, and calculate its change when a van der Waal's gas with a = 4.14 atm L²mol-² and b = 5.15 x 10-2 Lmol-¹ is cooled from 200°C to 10°C.

At the critical point for carbon dioxide, the substance is very far from being an ideal gas. Prove this statement by calculating the density of an ideal gas in g/cm3 at the conditions of the critical point and comparing it with the experimental value.
