0.05\,\text{kg}

of ice at

0^{\circ}\text{C}

is added to

0.20\,\text{kg}

of water at

30^{\circ}\text{C}

contained in a calorimeter of water equivalent

0.015\,\text{kg}

. The final equilibrium temperature is

10^{\circ}\text{C}

. Using these observations, determine the latent heat of fusion of ice. (a)

3.61\times10^{5}\,\text{J kg}^{-1}

(b)

3.2\times10^{5}\,\text{J kg}^{-1}

(c)

2.94\times10^{5}\,\text{J kg}^{-1}

(d)

3.40\times10^{5}\,\text{J kg}^{-1}
