The temperature of 2.7 kg of water is 34° C. To cool the water,
ice at 0° C is added to it. The desired final temperature of the
water is 11° C. The latent heat of fusion for water is 333.5 ×
103 J/kg, and the specific heat capacity of water is
4186 J/(kg·C°). Ignoring the container and any heat lost or gained
to or from the surroundings, determine how much mass m of
ice should be added.

The temperature of 2.26 kg of water is 34 °C. To cool the water, ice at 0 °C is added to it. The desired final temperature of the water is 11 °C. The latent heat of fusion for water is 33.5 × 104 J/kg, and the specific heat capacity of water is 4186 J/(kg·C°). Ignoring the container and any heat lost or gained to or from the surroundings, determine how much mass m of ice should be added.

How many grams of ice at -15°C must be added to 705 grams of water that is initially at a temperature of 88°C to produce water at a final temperature of 11°C. Assume that no heat is lost to the surroundings and that the container has negligible mass. The specific heat of liquid water is 4190 J/kg·C° and of ice is 2050 J/kg·C°. For water the normal melting point is 0.00°C and the heat of fusion is 334 × 103...
