I don't think heat of fusion has much to do with overall
temperatures. That's really just a little bit of hysteresis in the
freeze/melt cycle.


Ice has a heat capacity of 0.502 BTU/lb-°F and a
heat of fusion of 143 BTU/lb.
Liquid water has a heat capacity of 0.999 BTU/lb-°F
(I don't know why it's not exactly 1.0000 -- it should
be IIRC) and the same heat of fusion (naturally).

Thus it takes as much heat to melt one pound of
ice (same temp) as it does to raise the resulting
water to 175 degrees F.

Note that the heat capacity of ice is much less
than liquid water's.

BTW, For those of you with an interest in materials
(water & ice are but two) see http://matweb.com/

Try the search function by name ... or you can
search in many other ways, such as min/max
elemental composition for alloys, etc.
