A 897g copper pan is removed from the stove at a temperature of 150 C. It is then stacked on top of a 607 g aluminum sheet at room temperature, 25 C. The specific heat capacity for copper is 0.387 J/g·K and that for aluminum is 0.904 J/g·K. Assume no heat is gained or lost to the surroundings. What is the final temperature ( f) of the two objects after thermal equilibrium is reached?
