Latent Heat
The amount of heat absorbed or released by unit mass of substance during change of state of substance without changing nits temperature is called latent heat.
Latent Heat Formula
Latent Heat Formula is given as
L = Q / m
where
- m is mass of substance
- Q is amount of Heat Absorbed
Latent Heat in Phase Transitions
Latent Heat of Fusion: The amount of heat absorbed by unit mass of substance during its conversion from solid state to liquid state at its melting point is called latent heat of fusion.
Latent Heat of Vaporisation: The amount of heat absorbed by unit mass of substance during its conversion from liquid state to gaseous state at its boiling point is called latent heat of vaporisation.
- Latent heat of fusion of ice is 80 cal / g.
- Latent heat of vaporisation of water is 540 cal/ g.

Thermal Properties of Matter
Thermal Properties of Matter refer to the characteristics and behaviors of substances related to heat and temperature. These properties play a crucial role in understanding how materials respond to changes in temperature and how they conduct store, or transfer heat. Some of the key thermal properties of matter include temperature, heat capacity, specific heat capacity, thermal conductivity, thermal expansion, phase change, melting, and boiling point, among others.
In this article, we are going to explore how temperature changes affect various properties of matter. We will discuss different thermal properties that are important to study to understand the nature of any material and the effects caused by temperature changes on it.
