Initially you have mW = 3.4 kg of water at
TW = 54°C in an insulated container. You add
ice at TI = -21°C to the container and the mix
reaches a final, equilibrium temperature of Tf
= 25°C. The specific heats of ice and water are
cI = 2.10×103J/(kg⋅°C) and
cW = 4.19×103 J/(kg⋅°C),
respectively, and the latent heat of fusion for water is
Lf = 3.34×105 J/kg.

In an insulated container of negligible mass, 900 g of water at 25.0oC is mixed with 765 g of ice at -18.0oC. After several minutes, it is observed that only part of the ice has melted and that the remaining ice is in thermal equilibrium with the surrounding water. What is the temperature of the unmelted ice? Calculate the heat lost by the 900g of water. Calculate the mass of ice that is melted in this process. The specific heat...

You drop an ice cube into an insulated container full of water and wait for the ice cube to completely melt. The ice cube initially has a mass of 80.0 g and a temperature of 0°C. The water (before the ice cube is added) has a mass of 660 g and an initial temperature of 20.0°C. What is the final temperature (in °C) of the mixture? (Assume no energy is lost to the walls of the container, or to the...
