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.
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.
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.
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.

Equation. Consider m grams of a liquid that requires q Joules of energy to change its state completely from liquid to gas. Then, the heat of vaporization (ΔH vap) is given by the following formula. ΔH vap = q/m. Symbol: ΔH vap. Unit: Joules/gram (J/g), kiloJoules/kilogram (kJ/kg), or calories/gram (cal/g) Note that ΔH vap > 0.
