If a drop of liquid breaks into smaller droplets, it result in lowering of temperature of the droplets. Let a drop of radius R, breaks into N small droplets each of radius r. Estimate the drop in temperature.

Explanation

To solve the problem of estimating the drop in temperature when a drop of liquid breaks into smaller droplets, we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Volume Conservation**:
- A large drop of radius \( R \) breaks into \( N \) smaller droplets, each of radius \( r \).
- The volume of the large drop is given by:
\[
