Latent heat is the amount of energy that is needed to change the state of matter. Either from a solid to a liquid, from a liquid to gas or vice versa. For example if you boil a kettle of water, energy or latent heat is added to the water from the element within the kettle. The water will heat up and eventually turn to steam.

Latent Heat


Can latent heat be zero?

No, latent heat can never be zero.Because latent heat is the hidden heat so there has to be heat more than zero.

Why is latent heat important to the atmosphere?

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.


Why latent heat is called latent?

The term was introduced around 1762 by Joseph Black. It is derived from the Latin latere (to lie hidden). Black used the term in the context of calorimetry when referring to the heat transferred that caused a change of volume while the thermodynamic system was held at constant temperature.In contrast to latent heat, an energy is called a sensible energy or heat, when it causes processes that do result in a change of the temperature of the system.-Wikipedia


Why is latent heat of vapourisation higher than latent heat of fusion?

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.


What is the heat that is released when water condenses and changes to liquid form?

The latent heat of vaporisation.


Definition of refrigeration?

The transfer of heat from one space to another. Usually using latent heat evaporation in the evaporator coil, rejecting it in the latent heat of condensation in the condensor coil, using the compressor to pump the refrigerant and the metering device to cause a pressure and therefore temperature drop.
