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
