Find the mass of an empty calorimeter (coffee cup and lid).Then, fill it about 2/3 full of water, having a temperature ofabout 35oC and again, find the mass.
Stirthewaterinthecalorimeterandreadtheinitialtemperature,ofthewater,
to the nearest tenth of a degree.

on the calorimeter as quickly as possible.

Calculate the latent heat of fusion of ice and compare with thestandard. It
should be noted, the calorimeter itself and the stirring rod areconsidered to be
negligible in this experiment.
Repeat the experiment, only using an aluminum calorimeter.
