Water has a high latent heat of combination, so transforming water into ice requires expulsion of more vitality than solidifying fluid oxygen into strong oxygen, per unit gram. Latent heat of vaporization – water at 0.1 MPa (atmospheric pressure) h lg = 2257 kJ/kg. Specific Latent Heat Specific latent heat is characterized as the measure of warm vitality (heat, Q) that is consumed or discharged when a body experiences a steady temperature process. Material Properties - Material properties for gases, fluids and solids - densities, specific heats, viscosities and more ; Water has a high latent heat of combination, so transforming water into ice requires expulsion of more vitality than solidifying fluid oxygen into strong oxygen, per unit gram. Specific Latent Heat Specific latent heat is characterized as the measure of warm vitality (heat, Q) that is consumed or discharged when a body experiences a steady temperature process. Water is an excellent means of controlling temperature due to its unusually high capacity for latent heats of fusion and evaporation. Air heats as it crosses warm water and picks up water vapor. All properties are given in both SI and imperial units. The enthalpy of vaporization is a function of the pressure at which that transformation takes place. Latent heat of vaporization: Heat necessary to transform 1 kg of ebullient water into vapour without change of temperature (thermal energy necessary during the change of state liquid to the state vapour). Therefore, changing a given quantity of water to steam requires 5.4 times as much heat as warming it from 0°C (+32°F) to 100°C (212°F), and melting ice requires as much heat as warming water from 20°C (68°F) to 100°C. of liquid ammonia at its saturation pressure For example, the latent heat of vaporization of water is 540 cal/g and the latent heat of freezing of water is 80 cal/g. The (latent) heat of vaporization (∆H vap) also known as the enthalpy of vaporization or evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance, to transform a given quantity of the substance into a gas..

Water is an excellent means of controlling temperature due to its unusually high capacity for latent heats of fusion and evaporation. Let us calculate latent heat by a simple expression: Determine the latent heat of a 10kg substance if the amount of heat for a phase change is 200k.cal.
