A copper cylinder (c=390 J/kg K) with a mass of 75 g is placed in a furnace at a temperature of 312 °C (585 K), until it reaches thermal equilibrium. It is then quickly dropped into an insulated container containing 220 mL of water (c=4190 J/kg K). The heat capacity of the container is 190 J/kg K. Initially, the water and the container have a temperature of 12°C (285 K). For the experiment determine the following: a) The complete mathematical equation that models the behavior of the system. b) Indicate the energy transfer mechanisms that take place in the system. c)The laws of thermodynamics that delimit the behavior of the system. d)Calculate the final temperature of the system at equilibrium.
