The symbol for latent heat is ( L ).
Latent heat is the energy absorbed or released during a phase change, such as when water evaporates or condenses. In the atmosphere, when air cools and reaches its dew point, water vapor condenses, releasing latent heat and warming the surrounding air. Conversely, when air warms and evaporates water, it absorbs latent heat and cools the surrounding air. This process affects the temperature and stability of the air mass.
The formula to calculate the latent heat of fusion is Lf = Q / m, where Lf is the latent heat of fusion, Q is the amount of heat added or removed during the phase change, and m is the mass of the substance undergoing the phase change.
Latent heat of evaporation of water to steam is 2270 KJ/Kg
Latent
The opposite of latent heat is sensible heat. Sensible heat is the heat that causes a change in temperature of a substance without a change in phase.
The energy which must be transferred to or from a sample of water in order to change it's state is called the Latent Energy or Latent Heat - for example Latent Heat of Evaporation or Latent Heat of Freezing.
Latent heat is an important form of atmospheric energy. Latent heat is a property of water vapor in the atmosphere and when water vapor condenses it releases latent heat. Latent heat must be supplied to evaporate liquid water and this heat affects the behavior of the weather.
Latent heat is the heat required to achieve a change of phase - for example, to melt ice and convert it to water. As to the relationship with potential energy, latent heat IS a type of potential energy.
Split heat may refer to a heating system that utilizes a heat pump with two main components - an indoor unit (evaporator) and an outdoor unit (condenser). The indoor unit absorbs heat from the ambient air, while the outdoor unit releases that heat into the surrounding environment. This setup allows for efficient heating and cooling of a space.
latent heat of vapourisation is the heat energy required to change 1 kg of a liquid to gas at atmospheric pressure at its boiling point where latent heat of fusion is the amount of heat energy required to change 1 kg of solid to liquid at its melting point so that is why latent heat of vapourisation higher than latent heat of fusion.
The latent heat of vaporisation of water requires more energy. This is because on melting, the intermolecular bonds in water are only weakened whereas on boiling, the bonds are completely broken, which requires a larger amount of energy.
