Consider phase transitions in conditions of variable pressure, volume and temperature. In the phase diagram for a single component system, the critical point defines the pressure, Pc, and temperature, Tc, at the end of the liquid-vapour co-existence line in P-T coordinates. How does the expression c' c for the van der Waals gas compare Tc PV to the equivalent expression for an ideal gas? Explain the origin T of any difference, giving as much detail as possible.

Osmotic pressures are often reported in units of atmospheres or mm Hg. The latter impliesthat the height of a column of liquid can be used as a measure of pressure. This is, in fact, thebasis of the torricellian barometer from which the units of “torr” come. The pressure, P, isrelated to the height of the column by:P = ρghwhere ρ is the density of the liquid, g is the acceleration due to gravity and h is the height. Whatwill be the height (in mm) of a column of aqueous solution with a density of 0.9987 g/mL, if theosmotic pressure of the solution at 25 °C is 1.4 mm Hg? The density of mercury at thistemperature is 13.8 g/mL
