Dalton's Law

  1. Sep 3, 2006 #1
    Can anyone explain to me, using Dalton's Law, why a fresh cup of tead made with boiling water is not as hot at higher altitudes as it is at sea level?

    I know the law is:

    the law that the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of the gases of the mixture.

    But how to relate it, I have no idea.

    When you heath water, the water pressure augment at the interface between water and air
    The boiling point of water vary with the pressure of the atmosphere.
    At sea level the boiling point is 100 ˚C where the air pressure is highest.

    At higher altitude the pressure of the atmosphere is getting lower,so it make easier to water to boil.
