The change of state from liquid to solid by the release of heat ………..

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

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

Evaporation is the change of state from liquid to vapour by absorbing heat at a particular temperature.

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

Change of a solid to a liquid

Assertion : In change of state from solid to liquid the temperature decreases untill the entire amount of the solid subtance melts. Reason : The phenomenon of refreezing is called melting

The change of state from a liquid into a vapour at a temperature below the boiling point is ...................... (evaporation/condensation)

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.

The rapid change of state from liquid to vapour at a particular temperature

Name the terms for the following : (a) The change of a solid into liquid. (b) The force of attraction between the molecules of matter. (c) The particles of matter which may or may not have independent existence. (d) The process due to which a solid directly changes into its vapours. (e) The change of vapour into a liquid.
