Physics

A 40-g block of ice is cooled to

−69°C

and is then added to 570 g of water in an 80-g coppercalorimeter at a temperature of 23°C. Determine the finaltemperature of the system consisting of the ice, water, andcalorimeter. (If not all the ice melts, determine how much ice isleft.) Remember that the ice must first warm to 0°C, melt, and thencontinue warming as water. (The specific heat of ice is 0.500 cal/g· °C = 2,090 J/kg · °C.)
