as the pressure on a liquid is changed from 100.kPa to 120.kPa, the temperature at which the liquid will boil

decease
increase
or remain the same ?

  • Chem -

    The boiling point is defined as the temperature at which the vapor pressure of the liquid equals the atmospheric pressure. So as the pressure is increased, the vapor pressure must be higher if pressure is higher and how do we get a higher vapor pressure. Lower T or higher T?
