Question

How accurate is the following description (quoted) of what happens when a liquid is heated in a closed vessel?

Answer 1

Boiling does not occur when liquid is heated in a closed vessel . on heating continuously the vapour pressure increases. at first the boundary is visible between the liquid and vapour phase because liquid is more denser than vapour. as temperature increases more and more molecule go to Vapour phase and density of vaporizers. at same time the liquid becomes less dense. it extends because molecules move apart. when the density of liquid and vapour becomes the same; the clear boundary between the two phase disappears. this temperature is called critical temperature....
