A 145 g aluminum cylinder is removed from a liquid nitrogen, Ask an Expert

Academics

A 145 g aluminum cylinder is removed from a liquid nitrogen bath, where it has been cooled to -196° C. The cylinder is immediately placed in an insulated cup containing 226 g of water at 15.0° C,. What is the equilibrium temperature of this system? If your answer is 0° C, determine the amount of water that has frozen. The average specific heat of aluminum over this temperature range is 653 J/(kg · K).
