If the temperature above which van der Waals gas cannot be liquefied is 32.3 and minimum pressure to be applied at that temperature for liquefaction be 48.2 atm. Determine the diameter of gas molecule. [2 marks] Calculate "a" and hence pressure of 60gm of the gas at 27 with a volume of 2 litres if its molecular weight is 30.
