A 40-g block of ice is cooled to -78.0 degree C and then added to 560-g of water in an 80-g copper calorimeter at a temperature of 25.0 degree C. 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 0 degree C, melt and then continue warming as water. The specific heat of...
