Latent heat of vaporization is the heat consumed or discharged when matter disintegrates, changing state from fluid to gas state at a consistent temperature. The heat of vaporization of water is the highest known.
Jul 3, 2023 · Latent heat is of two types: 1) Latent Heat of Fusion 2) Latent Heat of Vaporisation. Latent Heat of Fusion. The latent heat of fusion or melting of solid is the quantity of heat in joules required to convert 1 kg of solid to liquid, without any change in temperature.
“The amount of heat that is needed to convert a unit mass of liquid substance into a gaseous phase at constant temperature conditions is known as latent heat of vaporization.” An example of the process that involves latent heat of vaporization is the conversion of liquid particles into water vapors.
The latent heat of vaporisation of a liquid is the quantity of heat in joules required to convert 1 kilogram of the liquid (at its boiling point) to vapour or gas, without any change in temperature. The latent heat of vaporization of water is 22.5×10 5 joules per kilogram (or 22.5×10 5 j/kg).
When a material in liquid state is given energy, it changes its phase from liquid to vapour without change in temperature, the energy absorbed in the process is called latent heat of vaporization. The latent heat of vaporization of water is about 2260 k J / K g which is equal to 40.8 k J / m o l.
Apr 16, 2024 · This is known as l atent heat of vaporization. The word ‘latent’ means hidden; till the liquid is entirely converted to the gaseous phase, the temperature remains constant as the heat is used as the energy required in the conversion. It refers to the change in enthalpy of the substance.
