11 godz. temu · By Carin Cain October 15, 2024June 18, 2024. A heat of vaporization calculator simplifies the calculation of the energy required to convert a liquid into vapor at constant temperature. It uses the latent heat of vaporization, specific heat capacity, mass, temperature change, and heat added to determine the amount of heat needed.
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.
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.
El-Dessouky and Ettouney (2002) proposed a correlation for the latent heat of vaporization of pure water (L. w) in kJ/kg in terms of temperature (T) in C is given in Eq. (6.9), and related constants are provided in Table 6.3. L. w = b. 1 + b. 2. T + b. 3. T. 2 + b. 4. T. 3 (6.9)
The heat \(Q\) required to change the phase of a sample of mass \(m\) is given by \[ Q = mL_f (melting/freezing),\] \[Q = mL_v (vaporization/condensation),\] where the latent heat of fusion, \(L_f\), and latent heat of vaporization, \(L_v\), are material constants that are determined experimentally.
