Heat of Fusion of Ice?

Question

Can someone explain the equation and define each term to me?

mcpΔT = mcoΔT + mΔH

Thank you

Answer 1

m = mass
ΔT = change in temperature
ΔH or ΔHf (in this case) = Heat of Fusion
cp = specific heat at constant pressure (c for specific heat, p for pressure)

I'm not sure what co is supposed to be.

The equation as I have always seen it is:
Q = mcpΔT + mΔHf + mΔHv
used when you are, for example, heating a solid until it melts, or cooling a liquid until it freezes.

Q is used to represent heat.
mcpΔT represents the energy needed to raise/drop the temperature of a substance.
mΔHf represents the energy required to melt/freeze the substance.
mΔHv represents the energy required to boil/condense the substance.

If one of those criteria did not occur, you just omit that relevant portion of the formula (so if it didn't boil/condense, then mΔHv = 0 and you ignore it.)
