Question

A 40-g block of ice is cooled to 76°C

A 40-g block of ice is cooled to76°C and is then added to630g of water in an 80-g copper calorimeter at a temperature of22°C. Determine thefinal 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 icemust first warm to 0°C, melt, and then continue warming as water. (The specific heat of iceis0.500 cal/g · °C = 2,090 J/kg · °C.)

Tf = °C
mice final = g
