WebbMelting point is the temperature at which a given solid substance changes its solid-state to liquid. Both the phases, i.e., solid and liquid, exist in equilibrium at the melting point. Therefore, the melting point of a given solid is equal to the freezing point of a liquid. For example, water shows equilibrium at 0°C. Water and ice at equilibrium The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapor.
