latent heat of condensation

Latent heat, characteristic amount of energy absorbed or released by a substance during a change in its physical state that occurs without changing its temperature. SUMMARY Latent heat capacity – is the amount of heat that will change the state of a substance at a specific temperature. An identical amount of calories (about 600 cal/g) is released in this process as was needed in the evaporation process. When heat is extracted from a substance, freezing, condensation and deposition may occur. Condensation is the reverse process, where heat in transferred away from a substance to its surroundings. Although water evaporate and becomes vapor, the vapor becomes water when it is cooled. Energy must be removed from the condensing particles to make a vapor condense. Latent Heat. Heat which is released during vapor becomes water is called heat of condensation. The temperature does not change during this process, so heat released goes directly into changing the state of the substance. It is expressed as kg/mol or kJ/kg. Latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature. 11. Latent heat of condensation is energy released when water vapor condenses to form liquid droplets. This is one mechanism of how thunderstorms maintain their intensity. Latent heat of condensation is the driving force behind all tropical cyclones. According to the different phases, it has different names like the heat of condensation, the heat of vaporization, etc. The latent heat is normally expressed as the amount of heat (in units of joules or calories) per mole or unit mass of the substance undergoing a change of state. When heat is added to a substance, melting, vaporization or sublimation may occur. The amount of heat energy absorbed or released for a phase change is known as latent heat. The heat of condensation is a heat of state change. Latent heat is the heat required to convert a solid into a liquid or vapor phase, or a liquid into a vapor phase. It is the same amount of energy as latent heat and two to five times larger compered with sensible heat. It is the heat released or absorbed during phase change. This is why condensation occurs on cold surfaces: the heat transfers energy away from the warm vapor to the cold surface. Formula of Latent Heat The latent heat of condensation is defined as the heat released when one mole of the substance condenses. Latent heat of condensation is energy released when water vapor condenses to form liquid droplets. This release of latent heat increases the temperature of the surroundings.
