Question

Define the following terms:
a) melting point b) boiling point c) evaporation

Answer 1

Melting point:Melting point is the temperature at which a solid becomes a liquid at normal atmospheric pressure.

Boiling point: Temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and liquid change to vapor (and vice versa).

Evaporation:Evaporation is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure.
