calculate the amount of heat required to change 5 pounds of ice at 32 degrees to water 32 degrees

2 answers

q to melt ice
mass ice(in grams) x heat fusion.

Is that 32 F or 32 C. If 32 C, that will be
q = mass melted ice x specific heat x (Tfinal-Tinitial)

Then add the two qs together.

5 lbs x 144 Btu / lbs = 720 Btu
