Hi, and thanks for looking
I'm doing a heat of fusion lab for school and I'm having trouble trying to find the equations that would solve the following: Q (heat) released by liquid cooling down Q (heat) absorbed by melted ice warming up Q (heat) absorbed by ice while melting /\ (delta or change of something) H fus of H2O. The specific heat of alcohol Any help would be great. THanks again.

the specific heat of ice while melting is 2.06 J/gC
the specific heat of water is 4.18 J/gC the heat of fusion is 334 J/g my chem is a little rusty but isnt the delta H = to the change in temp (degrees C). Now just set up ur problem first by writing out the knowns and unkowns.

It would help to know what you are trying to calculate, and from what. These may be useful : 1. Total heat lost by A = total heat gained by B (assuming no heat escapes) 2. During heating/cooling, Q = mC/\T, m:mass, C:sp. heat cap. 3. During boiling/melting/freezing, Q = mL, L:latent heat
