The enthalpy of vaporization is positive because energy is required to break the intermolecular forces holding liquid molecules together and convert them into vapor. This energy input is needed to overcome the attractive forces between the molecules in the liquid phase.
The enthalpy of vaporization for chloroform is approximately 31.4 kJ/mol.
The standard enthalpy change of vaporization for CDDT (Clotrityl chloride) is approximately 42 kJ/mol.
The enthalpy of fusion is the heat energy absorbed or released when a substance changes from solid to liquid at its melting point. The enthalpy of vaporization is the heat energy absorbed or released when a substance changes from liquid to gas at its boiling point.
Enthalpy is a state function, and to a first approximation does not depend on temperature. So the change in enthalpy to go from solid to a gas directly (sublimation) at some temperature is equal to the sum of the enthalpies associated with going from a solid to a liquid (fusion) and going from a liquid to a gas (vaporization) at other temperatures.
Metallic bond strength refers to the amount of energy as heat required to vaporize the metal. The enthalpy of vaporization is defined as the amount of energy absorbed as heat when a specified amount of substance vaporizes at constant pressure. Metallic bond strength increases as the enthalpy increases.

To determine the heat of vaporization of nitrogen, you would need the enthalpy of vaporization data for nitrogen. This value is typically around 5.57 kJ/mol at its boiling point of -195.79°C. By knowing the enthalpy of vaporization and the conditions at which nitrogen is boiling, you can calculate the heat of vaporization.
The enthalpy of fusion is the heat energy absorbed or released when a substance changes from solid to liquid at its melting point. The enthalpy of vaporization is the heat energy absorbed or released when a substance changes from liquid to gas at its boiling point.
The latent heat of evaporation
The enthalpy of vaporization is different.
Vaporization is the phase transition from liquid to vapor and is equivalent to the enthalpy change of vaporization in thermodynamics. This enthalpy change represents the amount of energy required to convert a substance from liquid to vapor at its boiling point. It is a key parameter in understanding the behavior of substances during phase transitions.
The necessary heat is called enthalpy of vaporization.
The enthalpy of vaporization is increased.
Enthalpy is a state function, and to a first approximation does not depend on temperature. So the change in enthalpy to go from solid to a gas directly (sublimation) at some temperature is equal to the sum of the enthalpies associated with going from a solid to a liquid (fusion) and going from a liquid to a gas (vaporization) at other temperatures.
Enthalpy is used to calculate the energy required to vaporize a volume of liquid by applying the concept of latent heat of vaporization, which is the amount of energy needed to convert a unit mass of liquid into vapor without changing its temperature. The total energy required for vaporization can be calculated by multiplying the mass of the liquid by the specific enthalpy of vaporization (ΔH_vap) at the given temperature. This relationship allows us to determine the total energy input necessary to achieve complete vaporization of the liquid.
Metallic bond strength refers to the amount of energy as heat required to vaporize the metal. The enthalpy of vaporization is defined as the amount of energy absorbed as heat when a specified amount of substance vaporizes at constant pressure. Metallic bond strength increases as the enthalpy increases.
