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.
The formula is: Q = mL Q = mL. where: m\ \rm [kg] m [kg] — Mass of the body; L\ \rm [kJ/kg] L [kJ/kg] — Specific latent heat; and. Q\ \rm [kJ] Q [kJ] — Heat absorbed or released depending on the direction of the transition. The specific latent heat is different for solid-to-liquid transition and liquid-to-gas transition.
17 lip 2023 · The latent heat of vaporization formula is written as L = Q/m, which was gotten from Q = mL. Where: Q = Quantity of heat in joules (J), m = mass of substance in kg, L = specific latent heat of vaporization in J/kg. Additionally, if the heat is supplied from an electric heater, the following equations apply.

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.
The latent heat of vaporization is the amount of heat needed to cause a phase change between liquid and gas. L f L f and L v L v are coefficients that vary from substance to substance, depending on the strength of intermolecular forces, and both have standard units of J/kg.
