Latent Heat of Fusion of Ice

  1. Mar 5, 2009 #1
    I did a lab experiment were we measured the latent heat of fusion of ice but im not quite sure what that is. I read that latent heat of fusion is the energy(heat) it takes to change liquid to solid. Is that true? Why would it take heat to freeze something?

    Confusion like that is why 'latent heat of fusion' is now referred to as 'enthalpy of fusion' instead.

    And in the case of water it doesn't require energy, melting is exothermic and freezing is endothermic.
    By the same amount.
