Define latent heat in geography
WebLatent Heat Definition. Due to the difference in the temperature of the two materials, heat energy can be transmitted from one material to another. It is a kind of kinetic energy linked to the irregular movement of a substance's constituent particles. The letter Q frequently represents heat energy, expressed in joules. WebThe specific latent heat of a substance is the amount of energy needed to change the state of 1 kg of the substance without changing its temperature. Each substance has two specific latent heats:

WebIf the rising air gets saturated at this temperature (25°C), the latent heat of condensation returns back to the rising air and hence it cools at the wet adiabatic lapse rate (5°C per 1000m). Thus, the rising air becomes warmer and unstable, Conditional instability may occur only when the normal lapse rate ranges between dry adiabatic and ...

WebLatent heat, also called heat of transformation, is the heat given up or absorbed by a unit mass of a substance as it changes from a solid to a liquid, from a liquid to a gas, or the reverse of either of these changes. It is called latent because it is not associated with a change in temperature. Each substance has a characteristic heat of ...

WebSublimation. Figure 1: A piece of solid carbon dioxide (dry ice) sublimating from a solid directly into a gas. [1] Sublimation is a type of phase change that takes place when a solid turns directly into a gas, skipping the liquid phase. The opposite of sublimation is vapour deposition. The term "sublimation" only applies to a physical change of ...
WebThe term is used in contrast to a latent heat, which is the amount of heat exchanged that is hidden, meaning it occurs without change of temperature. For example, during a phase change such as the melting of ice, the temperature of the system containing the ice and the liquid is constant until all ice has melted.
