Problem

During an experiment to estimate the latent heat of fusion of ice,

0.12\,\text{kg}

of ice at

0\,^{\circ}\text{C}

is added to a copper calorimeter containing

0.30\,\text{kg}

of water at

35\,^{\circ}\text{C}

. The water equivalent of the calorimeter is

0.02\,\text{kg}

. After the ice melts completely and thorough stirring, the final temperature of the system is

5\,^{\circ}\text{C}

. (Specific heat capacity of water

=4200\,\text{J\,kg}^{-1}\,\text{K}^{-1}

.) (i) Construct the thermal energy balance for the system, clearly identifying each term involved. (ii) Calculate the latent heat of fusion of ice from the measurements.
