Condensation refers to the change of state from liquid to gas on cooling.

Which process refers to the change of state from liquid to solid?

The change of state from liquid to gas that takes place at the surface of a liquid

Explain the change of state from solid to liquid on the basis of kinetic theory.

Out of the compounds below, the vapour pressure of (B) at a particular temperature is

Name the following Change of state from vapour to liquid .

A solid material is supplied with heat at a constant rate. The temperature of the material is changing with heat input as shown (i) AB: change of state from solid to liquid. CD: change of state from liquid to vapour (ii) When CD=2AB , i.e., latent heat of vapourization is twice the latent heat of fusion of the substance. (iii) The reciprocal of slope of DE represents the heat capacity of vapour state of substance . (iv) If slope of OAgt slope of BC, i.e., specific heat of liquid state is greater than specific heat that of solid state.

Observe the graph given below and answer the following questions: During vaporization of a liquid, certain amount of heat is absorbed without any change in temperature. Which part of the graph shows this change?
