A 40-g block of ice is cooled to
−71C
and is then added to 590 g of water in an 80-g copper calorimeter at a temperature of 27C. Determine the final temperature of the system consisting of the ice, water, and calorimeter. (If not all the ice melts, determine how much ice is left.) Remember that the ice must first warm to 0C, melt, and then continue warming as water. (The specific heat of ice is 0.500 cal/g C = 2,090 J/kg C.)
Tf = ? (C)
mass of ice final (g)
