Vaporization means that the particles eg water molecules must have enough energy to break the liquid particle to particle bonds and form a gas particle. This happens at any temperature but happens for all molecules at the boiling point of the liquid. Some substances do not spontaneously go through a liquid phase but actually form a gas from the solid phase. Solid directly to gas is called sublimation but it is, in effect, a type of vaporization.

JudyVaporization is the process by which a substance changes from a liquid or solid state to a gaseous state. This typically occurs when the substance is heated to its boiling point or sublimation point. Energy is required for vaporization to overcome the intermolecular forces holding the substance together.

What are two types of vaporization?
The two main types of vaporization are evaporation, which occurs at the surface of a liquid at any temperature, and boiling, which occurs throughout the bulk of a liquid at a specific temperature called the boiling point.
What is the engery required to go from liquid to gas called?
The energy required to go from liquid to gas is called heat of vaporization. This is the amount of energy needed to change a substance from a liquid into a gas at constant temperature and pressure.
Calculate the entropy of vaporization per mole of ethanol Given enthalpy change is 109.8 JK-1 mol-1 and boiling point of ethanol is 78.50C?
The entropy of vaporization can be calculated using the equation ΔSvap = ΔHvap/Tb, where ΔHvap is the enthalpy of vaporization, Tb is the boiling point in Kelvin (351.65 K), and R is the gas constant (8.314 J/molK). Plugging in the values, we find ΔSvap ≈ 0.316 J/Kmol.
What is a change of a liquid to a gas called?
The change of a liquid to a gas is called vaporization or evaporation.
What is the Latent heat of vaporization for ethyl acetate?
The latent heat of vaporization for ethyl acetate is approximately 28.44 kJ/mol. This is the amount of energy required to convert one mole of liquid ethyl acetate into vapor at its boiling point.
