Question

Suppose two 45-g ice cubes are added to a glass containing 500 cm3 of cola at 20,0°C.
When thermal equilibrium is reached, all the ice will have melted, and the temperature of
the mixture will be somewhere between 20,0°C and 0°C. Calculate the final temperature
of the mixture. You may assume that the cola has a density and specific heat capacity the
same as water namely:
Density = 1,0 g/cm3 and specific heat = 4,184 J/gK
The heat of fusion (of water) is 333J/g.
[Hint: You should take into account that the 90g of water formed when the ice melts, must
be warmed to the final temperature
