Give reasons for the following.
Heat supplied/released during a change of state is called latent heat.
Which of the following energy is absorbed during the change of state of a substance?
(a) specific heat (b) latent heat (c) heat capacity (d) heat of solution
It has been observed that temperature remains constant till all solid melts into liquid. The heat supplied is used for changing a solid state into its liquid state by overcoming the particle-particle attraction force. The solid substance absorbs heat energy without showing any rise in temperature. This heat energy is called latent heat. The amount of heat required to convert a unit mass of a solid into its liquid state, without a change in temperature (i.e. at its melting point) is called the latent heat of fusion.EXPLAIN
