"WebFor 3 phases to co-exist, C = 1, P = 3 and F = 1 - 3 - 2 = 0. Here there is no degree of freedom. Thus ice, water and water vapour can only co-exist at one temperature and pressure, a point on the phase diagram known as the triple point. When the number of components is increased the number of degrees of freedom increases. " - Freezing point of biphenyl
