Solution:
QUESTION: 7

At triple point of a pure substance

Solution:

The Triple point is a line on the P - v diagram where all the three phases solid, liquid and gases exist in equilibrium. At a pressure below the triple point line, the substance cannot exist in liquid phase and the substance when heated, transforms from solid to vapour by absorbing the latent heat of sublimation from the surroundings.
