The enthalpy of evaporation at zero Kelvin is the amount of energy required to convert a substance from a liquid to a gas at absolute zero temperature.
Enthalpy is a fundamental concept in thermodynamics and is used to describe the energy of a system. Understanding enthalpy basics allows scientists to make accurate predictions and calculations about chemical reactions and physical processes.
The enthalpy of evaporation at zero Kelvin can be calculated using the Clausius-Clapeyron equation, which relates the enthalpy of vaporization to the temperature and pressure of a substance.
No, the enthalpy of evaporation at zero Kelvin cannot be negative. This is because at absolute zero temperature, all molecular motion ceases and there is no energy available for a substance to change from a liquid to a gas.
The enthalpy of evaporation at zero Kelvin is often referred to as the "latent heat of evaporation" because it is the energy required to overcome intermolecular forces and change the state of a substance from liquid to gas. At higher temperatures, the enthalpy of vaporization also takes into account the energy required to increase the temperature of the substance.
