Homework Help: Shaved ice thermodynamics help

  1. Mar 1, 2005 #1
    suppose that 3.1 kg of shaved ice is needed to keep medication cold in a room without a refrigerator. What amount o heat must be removed from the 3.1 kg of water to make ice once it has reached 0 deg C

    You need to know the enthalpy of formation for ice. Unless it says at certain temperature and press ure use the formation for STP>
    enthalpy of formation website:

    another nice site with the enthalpy of fusion of ice on it:

    What is the latent heat (at constant pressure,assumed atmospherical pressure,760 Torrs) for icing water/melting ice...?
