Latent Heat - Definition, Types, Formula, and Examples
2024年7月6日 · Latent heat is the heat required to transform a solid into a liquid or vapour phase. It is known by several names depending on its phase, such as the heat of condensation, the heat of vaporization, and so on. It can also refer to the quantity of heat energy received or emitted during a phase transition.
Latent Heat Formula - Equation, Solved Examples and FAQs
Latent Heat of Vaporization Formula. The heat absorbed or discharged as matter disintegrates, changing state from fluid to gas at a constant temperature, is known as latent heat of vaporization. The heat of water vaporization is the most well-known.
