The molar heat of vaporization, is the amount of heat (in kJ) it takes for one mole of a substance to transition from the liquid state to the vapor phase. Since we are not always working with exactly one mole of each substance, we will use this equation to Figure out the heat for the particular number of moles that we have according to the ...
Vaporization can be defined as the process in which liquid state changes into the vapour state. As a result of an increase in temperature, the kinetic energy of the molecules increases. Due to the increases in kinetic energy, the force of attraction between the molecules reduces.

The heat of vaporization, also called the enthalpy of vaporization or latent heat of vaporization, is the amount of energy required to transition from a liquid state to a gas or vapor state. The energy, in this case, remains positive, as the enthalpy must be added for the transformation to take place. The addition of heat induces more kinetic energ...
Water has a high heat of vaporization; water can require about 40.8 kilo-Joules per mole to vaporize. Hydrogen bonds can easily form between the oxygen and hydrogen molecules to form water. Energy is contained in this bond, which keeps the water at a lower energy state. In order to vaporize off this water, the temperature must be increased, which d...

May 1, 2013 · The molar heat of vaporization (Δ H vap) of a substance is the heat absorbed by one mole of that substance as it is converted from a liquid to a gas. As a gas condenses to a liquid, heat is released. The molar heat of condensation (Δ H cond) of a substance is the heat released by one mole of that substance as it is converted from a gas to a ...
