Question
**Problem Statement:**

If a piece of aluminum with a mass of 2.39g and a temperature of 100.0°C is dropped into 10.0cm³ of water at 14.1°C, what will be the final temperature of the system? 

*(Use 1.00g/cm³ as the density of water, Cₚ Al = 0.900 J/g°C)*

---

**Explanation of the Problem:**

- We are tasked with finding the final temperature when a hot piece of aluminum is placed in cooler water.
- The aluminum has a known specific heat capacity, mass, and initial temperature.
- The water has a known volume, which will be converted to mass using the given density.
- A heat exchange will occur, aiming for thermal equilibrium, meaning the same final temperature for both substances.

**Note:** The problem requires the use of the principle of conservation of energy, where the heat lost by aluminum will equal the heat gained by the water.
