Use the equations:



and



Using will give you the energy required for the ice to heat up to 0 C.

Then, you use to find the energy required to melt the ice to water at 0 C.

You should be provided with c, the specific heat capacity of ice and L the specific latent heat of fusion of ice.

Then, Q is the amount of heat,
m is the mass of the ice
theta is the change in temperature.

Post what you get! :)
