Consider a 27.5 g piece of ice at 0.00 C.

a) how much heat is required to convert the ice to water that is also 0.00 C?

b) how much heat would be required to warm this water from 0.00 C to 17.50 C?

HELP!!

I think the fusion is 333 J/g at 0 C... But I'm not sure what to do with that.

  1. Heat to melt=Hf*mass
    Heat to raisetemp=specificheat*changeTemp*mass

    Memorize those.

  2. is Hf triangleH'f?? and if so would the value be -285.83?


    for b, would we want the specific heat of h2o (l) or (s)?
