The latent heat calculator helps you compute the energy released or absorbed during a phase transition like melting or vaporizing. In the text below, we explain what is specific latent heat and present a simple latent heat calculation.
The latent heat of evaporation for water is 2256 kJ/kg at atmospheric pressure and 100oC. The heat required to evaporate 10 kg can be calculated as. q = (2256 kJ/kg) (10 kg) = 22560 kJ. Latent heat of vaporization for fluids like alcohol, ether, nitrogen, water and more.
L is the specific latent heat of vaporization and is the heat required to convert a unit mass of liquid into vapour at the same temperature as the boiling point. L and the boiling temperature, both depend on the pressure. Heat transfer occurs between bodies that are in contact with each other.
17 lip 2023 · Latent heat of vaporization L is the amount of heat energy required to change one kilogram of a substance from a liquid to a gas at constant temperature. Ensure consistent units for mass (kilograms, kg) and heat energy (joules, J) in the calculation.
Thermal properties of water at different temperatures like density, freezing temperature, boiling temperature, latent heat of melting, latent heat of evaporation, critical temperature and more. Thermodynamic properties of water: Boiling temperature (at 101.325 kPa): 99.974 °C = 211.953 °F.
In thermodynamics, the enthalpy of vaporization (symbol ∆Hvap), also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance to transform a quantity of that substance into a gas.
