A 0.0815 kilogram ice cube at 0 °C is dropped into a Styrofoam cup holding 0.349 kg of water at 13.1 °C.
Find the final temperature of the system. Suppose the cup and the surroundings can be ignored
Compute what is the amount of ice remaining?
Estimate the initial temperature of the water that would be enough to just barely melt all of the ice.
