A 837 g copper pan is removed from the stove at a temperature of 150 °C. It is then stacked on top of a 787 g aluminum sheet at room temperature, 25 °C. The specific heat capacity for copper is 0.387 and that for aluminum is 0.904 . Assume no g-K g-K heat is gained or lost to the surroundings. What is the final temperature (T;) of the two objects after thermal equilibrium is reached?

Question
**Problem Statement:**

A 837 g copper pan is removed from the stove at a temperature of 150 °C. It is then stacked on top of a 787 g aluminum sheet at room temperature, 25 °C. The specific heat capacity for copper is 0.387 \(\frac{J}{g \cdot K}\) and that for aluminum is 0.904 \(\frac{J}{g \cdot K}\). Assume no heat is gained or lost to the surroundings.

**Question:**

What is the final temperature (\(T_f\)) of the two objects after thermal equilibrium is reached?

\(T_f =\) \_\_\_\_\_ °C

**Diagram Explanation:**

The included image shows a copper pan placed on an aluminum sheet. This visual represents the physical setup for the described thermal equilibrium problem, where two different materials, initially at different temperatures, are coming into contact. The objective is to find the resulting equilibrium temperature when no heat is lost to the surroundings.
