Latent Heat in Phase Transition
Latent heat is the energy absorbed or released by a substance during a change in its physical state without a change in temperature. This phenomenon is most commonly observed during phase transitions, such as melting, freezing, vaporization, and condensation.
Latent Heat of Fusion
The latent heat of fusion is the amount of heat energy required to change a unit mass of a substance from solid to liquid at its melting point. For example, when ice melts into water at 0°C, it absorbs heat energy from its surroundings without increasing in temperature. This process requires a specific amount of energy, known as the latent heat of fusion.
Latent Heat of Vaporization
The latent heat of vaporization is the amount of heat energy required to change a unit mass of a substance from liquid to gas at its boiling point. For instance, when water boils at 100°C, it absorbs heat energy to transform into steam without a rise in temperature. This specific amount of energy is known as the latent heat of vaporization.
Example from Daily Life
A common example of latent heat in daily life is the process of sweating. When our body temperature rises, sweat glands secrete sweat, which evaporates from the skin, absorbing heat in the process. This absorption of heat helps to cool down our body, as the sweat undergoes a phase transition from liquid to gas by using the latent heat of vaporization.
