120 g of water at 28∘C28^\circ\text{C}28∘C is poured into an insulating cup. 60 g of ice at 0∘C0^\circ\text{C}0∘C is added to the water. The water is stirred until the temperature of the water has fallen to 0∘C0^\circ\text{C}0∘C.
18 g of ice remains unmelted.
The specific heat capacity of water is 4.2 J/g∘C4.2\text{ J/g}^\circ\text{C}4.2 J/g∘C.
Which value does this experiment give for the specific latent heat of fusion of ice?
