Answer 1

Explanation:

The enthalpy of fusion of a substance, also known as (latent) heat of fusion is the change in its enthalpy resulting from providing energy, typically heat, to a specific quantity of the substance to change its state from a solid to a liquid, at constant pressure.

Latent heat of vaporization is a physical property of a substance. It is defined as the heat required to change one mole of liquid at its boiling point under standard atmospheric pressure. It is expressed as kg/mol or kJ/kg. ... The heat of vaporization of water is about 2,260 kJ/kg, which is equal to 40.8 kJ/mol

Answer 2

Bubbling water on a stove happens when warm vitality from the heating component is moved to the pot and thus to the water. At the point when enough vitality is provided, fluid water grows to from water fume and the water bubbles. A gigantic measure of vitality is discharged when water bubbles are formed. Since water has such a high heat of vaporization, it’s anything but difficult to get scorched by steam.

Correspondingly, significant energy must be assimilated to change over fluid water to ice in a cooler. The cooler expels heat energy for permitting the stage progress to happen. Water has a high latent heat of combination, so transforming water into ice requires expulsion of more energy than solidifying fluid oxygen into solid oxygen, per unit gram.
