Question

State the melting point, specific heat capacity, specific latent heat of fusion and specific heat of vaporization of water.

Answer 1

Hint: The physical parameters such as melting point, boiling point, heat of vaporization change dramatically with the change in the temperature and pressure and the other physical factors also influence their magnitude.

Complete step by step answer:
-Melting point is defined as that temperature of the solid at which it changes from solid to liquid form under the atmospheric conditions. There exists equilibrium between the two states of matter that is the solid, liquid and the temperature of 273 K is considered to be the melting point of the water (ice).
-Boiling point of the liquid is the temperature at which the vapour pressure of the liquid becomes equal to the atmospheric pressure and because of that the liquid starts boiling. The boiling point of water is 100 degree Celsius.
-Specific heat capacity of the substance (Water) is the amount of the energy needed to change the temperature of 1 Kg of the substance by 1 degree Celsius.
-Specific latent heat of fusion of the water is the amount of heat energy required to convert 1 kg of water from ice to liquid state that is from the solid to the liquid state without any change in its temperature.
-The specific latent heat of vaporization of water is the amount of energy required to convert 1 kg of water from the liquid to the vapour state without the change in its temperature.

Note:
These physical parameters contribute to a very large extent on the different parameters for the determination of the different quantities in the chemical reactions such energy calculations are taken into consideration for different calculations.
