A glass thermometer (m = 13.0 g) is placed into a 110 g cup filled with 220 g of water. These objects have an initial temperature of 28°C. Pieces of ice with a mass of 49 g and starting at -5° is dropped into the cup and water. The equilibrium temperature of the system is 9°C. Find the specific heat of the cup. What is the closest material to this value?
