Step 1 of 5
Given the vapor pressure of nitrogen at several different temperatures, and here we need to find the heat of vaporization and normal boiling point of nitrogen.
The heat of vaporization is the amount of energy required to convert a given amount of a substance from a liquid state to a gaseous state at a constant temperature and pressure.
It is typically measured in units of joules per mole (J/mol) and is usually a positive value for most substances.
