A 240 g ice cube at 10 C is placed in an aluminum cup whose initial temperature is 70 C. The system comes to an equilibrium temperature of 20 C.
What is the mass of the cup?(answer in kg)

Write an equation that says the heat gained by the ice equals the heat lost by the cup. The only unknown will be the aluminum mass, which you can solve for. You will need to look up the specific heats of aluminum and ice. The heat of fusion of ice is 80 calories per gram, and will be part of the equation.
