The van der Waals equation for 1 mole of gas is given by (p +av-2)(v - b) = RT. In general, curves of p versus v forvarious values of T exhibit a maximum and a minimum at the twopoints where (δp/δv)T = 0. The maximum and minumum coalesceinto a single point on that curve where(δ2p/δv2)T = 0 inaddition to (δp/δv)T = 0. This point is calledthe "critical point" of the substance and its temperature,pressure, and molar volume are denoted by...
