critical point | critical point
The point at which saturated liquid and saturated vapour lines meet is called the critical point |The point at which fusion line and sublimation line and vapourisation meet is called the triple point
It is represented by a point on p-v-T surface |It is represented by a point on p-T diagram but appears as a line on p-v-T surface
At critical point there is no distinction between the liquid and vapour phases . below critical point the substances exists in a two phases | At triple point all the three phases can coexist together in equilibrium
