Why is a Calorimeter made up of thin sheets of the above material.

Explanation

**Step-by-Step Solution:**

1. **Identify the Material Used for Calorimeter:**
The calorimeter is typically made from thin sheets of copper.

2. **Reason for Using Copper:**
- **Good Conductor of Heat:** Copper is an excellent conductor of heat, which allows the calorimeter to quickly reach thermal equilibrium with the substance being measured. This means that the calorimeter can efficiently transfer heat to and from the contents, ensuring accurate temperature readings.
