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 given quantity of the substance into a gas .
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.
26 Ιουν 2023 · To a first approximation therefore the enthalpy of vaporization of a liquid is proportional to the thermodynamic temperature at which the liquid boils. This interesting result is called Trouton’s rule .
Water has a very high specific heat capacity of 4184 J/(kg·K) at 20 °C (4182 J/(kg·K) at 25 °C) —the second-highest among all the heteroatomic species (after ammonia), as well as a high heat of vaporization (40.65 kJ/mol or 2257 kJ/kg at the normal boiling point), both of which are a result of the extensive hydrogen bonding between its ...
30 Ιαν 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.
Enthalpy of Vaporization. Delve into the intriguing world of Engineering Thermodynamics, focusing on a key principle, the Enthalpy of Vaporization. This comprehensive guide provides a detailed understanding of what Enthalpy of Vaporization entails, as well as its unique characteristics.
The heat of vaporization is the enthalpy change when a unit mass of a substance changes its state from liquid to gas at a constant temperature and pressure. It is sometimes called enthalpy of vaporization or latent heat of vaporization.
