what is latent heat ?

Question

Answer

Answer

Latent heat is a type of energy used to one state of matter into another below it's boiling point.

Answer

Latent Heat:
Latent heat is the amount of heat energy required to change the state of a substance without changing its temperature. It is absorbed or released during a phase change, such as melting, freezing, vaporization, or condensation, at a constant temperature.

Types of Latent Heat:
- Latent Heat of Fusion: The heat energy required to change a substance from a solid to a liquid state, or vice versa, is known as the latent heat of fusion.
- Latent Heat of Vaporization: The heat energy required to change a substance from a liquid to a gas state, or vice versa, is known as the latent heat of vaporization.

Significance of Latent Heat:
- Latent heat plays a crucial role in weather phenomena, such as the formation of clouds, rain, and snow.
- It is also essential in various industrial processes like refrigeration, air conditioning, and distillation.

Examples of Latent Heat:
- When ice melts into water, it absorbs latent heat of fusion.
- When water evaporates into steam, it absorbs latent heat of vaporization.

Formula for Calculating Latent Heat:
- The formula to calculate latent heat is Q = mL, where Q is the heat energy, m is the mass of the substance, and L is the latent heat.

Conclusion:
Understanding latent heat is crucial in various fields, as it helps explain the energy involved in phase changes of matter. Its applications range from everyday phenomena to industrial processes, making it a fundamental concept in thermodynamics.
