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.
Homework Answers
From the law of thermodynamics Heat lost = Heat
gained
Heat gained by fusion + Heat gained by water formed from melted ice
= Heat lost by warm water
m * 33.5 × 10^4 + m * 11 * 4186 = 2.26 * (34 - 11) * 4186
m ( 381046) = 217588.28
m (mass of ice) = 0.571 KG
