In an experiment to determine the specific latent heat of fusion of ice using a container
with negligible heat capacity, a student obtained the following data:
Initial temperature of water = 30 °C
Final temperature of water + melted ice = 20 °C
Initial mass of water = 100 g
Final mass of water plus melted ice = 110 g
(i)
Calculate the heat lost by the water.
