A cube of ice is taken from the freezer at -7.8°C and placed in a 94 g nickel cup filled with 311 g of water. Both the water & the cup are at 20.8°C. Eventually the system reaches thermal equilibrium at 17.9°C. Determine Qcupr Qwater (for the water initially in the cup), Qicer & the mass of the ice. Qcup = Qwater = Qice = mice =
