An aluminium can of mass 
contains a mass of 
of warm water at a temperature of 
, as illustrated in the figure below.
A mass of 
of ice at 
is taken from a freezer and put into the water. The ice melts and the final temperature of the can and its contents is 
. Data for the specific heat capacity 
of aluminium, ice, and water are given in the table below.
Assuming no exchange of thermal energy with the surroundings,
show that the loss in thermal energy of the can and the warm water is 
,
use the information in (a) to calculate a value 
for the specific latent heat of fusion of ice.
.
