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 heat of vaporization of iron is the amount of heat energy required to convert one mole of liquid iron into vapor at its boiling point. For iron, this value is 6.47 kJ/mol. It is a measure of the strength of the attractive forces between iron atoms in the liquid state.
The heat of vaporization and heat of condensation are directly related and have the same magnitude but opposite signs. The heat of vaporization is the energy required to change a substance from liquid to vapor, while the heat of condensation is the energy released when a substance changes from vapor to liquid.

Heat vaporization, also known as heat of vaporization, is the amount of heat energy required to convert a liquid into a gas at its boiling point. This process occurs without a change in temperature. Heat of vaporization is an important property of a substance that determines its behavior during phase changes.
