Full Answer

When the vapor pressure drops below the atmospheric pressure, the substance changes its state of matter from a liquid to a gas. The kinetic energy of particles relates to the vapor pressure in a substance and is higher in a gas than in a liquid. Standard temperature and pressure conditions assume a temperature equal to 68 degrees Fahrenheit and that the pressure is one standard atmosphere unit.
