Homework Help: My book says that 'A liquid gets heated up when it evaporates'

  1. Aug 29, 2010 #1
    1. The problem statement, all variables and given/known data

    My book says that 'A liquid gets heated up when it evaporates'

    2. Relevant equations



    3. The attempt at a solution

    I heard the opposite- the liquid cools itself.
    Please help

    Re: Evaporation

    I agree with you. It takes energy to turn a liquid into gas, and this energy has to come from the surrounding environment, including the remaining liquid.
