In thermodynamics, the enthalpy of vaporization (symbol ∆H vap), also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy that must be added to a liquid substance to transform a quantity of that substance into a gas.
24 lut 2023 · Equation \ref {2} is known as the Clausius-Clapeyron Equation and allows us to estimate the vapor pressure at another temperature, if the vapor pressure is known at some temperature, and if the enthalpy of vaporization is known.
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.
30 sty 2023 · The Heat of Vaporization (also called the Enthalpy of Vaporization) is the heat required to induce this phase change. Figure \(\PageIndex{1}\): Heat imparts energy into the system to overcome the intermolecular interactions that hold the liquid together to generate vapor.
What is latent heat of vaporization. How to calculate it. Learn its equation, along with the symbol & unit. Also, learn molar heat of vaporization & a few problems.
Online calculator, figures and tables showing heat of vaporization of water, at temperatures from 0 - 370 °C (32 - 700 °F) - SI and Imperial units. 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 ...
The molar heat of condensation \(\left( \Delta H_\text{cond} \right)\) is the heat released by one mole of a substance as it is converted from a gas to a liquid. Examples of calculations involving the molar heat of vaporization and condensation are illustrated.
