A 991 g copper pan is removed from the stove at a temperature of 150 °C. It is then stacked on top of a 799 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?
