Question

Define latent heat? ​

Answer 1

Answer:

Latent heat is the energy absorbed by or released from a substance during a phase change from a gas to a liquid or a solid or vice versa

Answer 2

The answer to the given question is as follow:

Latent Heat:

• The energy associated with the physical state of water, which can easily change from solid to liquid to vapour and vice versa, is known as latent heat.
• Breaking apart the bonds that connect the molecules is required to transform to a higher energy state; melting 1 kg of ice into water requires 0.33 MJ, and vaporising 1 kg of water requires 2.56 MJ (evaporation).
• Despite the fact that this energy is stored in the volume, it does not manifest as a temperature change and is not detectable by humans. The highest energy state of water is water vapour, which can be measured in a variety of ways, including vapour density (v in kg m 3), vapour pressure, and mixing ratio.
