Latent Heat Formula: Types of Latent Heat Transfer, and Importance

WebbThe specific latent heat of vaporisation is defined as: The energy required to convert 1 kg between a liquid and a gaseous state with no change in temperature. This applies when vaporising a liquid or condensing a gas. When a liquid substance is vaporised, its temperature will stay constant until all of the substance has vaporised. WebbIn physics, chemistry, and thermodynamics, an equation of state is a thermodynamic equation relating state variables, which describe the state of matter under a given set of physical conditions, such as pressure, volume, temperature, or internal energy.
