The temperature at which a substance in its vapour state changes into its liquid state is called
Sublimation point
Vaporization point
Freezing point
Condensation point
Explanation for the correct option(s) (d) Condensation point
Hence (D) is the correct option.
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
