Sketch a graph to show the behaviour of Pressure with Volume as given by the van der Waals' Equation of State. Draw isotherms generated by this equation which are at the critical temperature, above the critical temperature, and below the critical temperature. Also, mark on the sketch the critical volume and the critical pressure for the gas.
To this vessel 8.6787g of Ne are added in such a way that no butane escapes. The total pressure of the vessel (at the same temperature) is 1420 torr. Calculate the volume of the vessel and the mass of the butane.
