If that is a bomb calorimeter it is important to maintain a constant volume. If it isn't a bomb calorimeter you want to minimize heat transfer out of or into the calorimeter set up.

Melting lead requires 5.91 cal/g. How many joules are required to melt 1.25 lb of lead? (1 lb = 45 g; 1 cal=4.18J)

Convert 1.25 lb to grams.
q = mass Pb x heat fusion = ? cal
Then convert to J.
Post your work if you get stuck.
