Energy required to change the state of a mass of liquid to a gas is known as ____
|
Specific Latent Heat of Fusion
|
|
Specific Heat Capacity
|
|
Boiling Energy
|
|
Specific Latent Heat of Vaporisation
|
Explanation:
Detailed explanation-1: -Latent heat of vapourisation is a physical property of a substance. When a material in liquid state changes its phase from liquid to vapour, the energy absorbed in the process; is known as latent heat of vapourisation. For eg: For water, it is 2260kJ/Kg or 40. 8kJ/mol.
Detailed explanation-2: -latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature.
Detailed explanation-3: -Like the solid/liquid phase change, the liquid/gas phase change involves energy. The amount of energy required to convert a liquid to a gas is called the enthalpy of vaporization (or heat of vaporization), represented as Hvap.
