All liquids evaporate to a certain extent. the pressure exerted by the gas phase in equilibrium with the liquid is called vapor pressure, pvap. the vapor pressure of a particular substance is determined by the strength of the intermolecular forces. but for any given substance, the vapor pressure only changes with temperature. the clausius-clapeyron equation expresses the relationship between vapor pressure and temperature:
