Consider the following specific heats
H2O(solid) = 2.09 J/g · ◦ C
H2O(liquid) = 4.18 J/g · ◦ C
H2O(gas) = 2.03 J/g ·◦ C.
The heat of fusion for water is 334 J/g and
its heat of vaporization is 2260 J/g. Calculate
the amount of heat required to convert 67 g
of ice at −30◦C completely to liquid water at
37◦C.
