Why is Kelvin scale of temperature better than celsius scale?

Explanation

### Step-by-Step Solution:

1. **Definition of Temperature Scales**:
- The Celsius scale (°C) is based on the freezing point of water (0°C) and the boiling point of water (100°C) at standard atmospheric pressure. It includes both positive and negative values.
- The Kelvin scale (K) is an absolute temperature scale that starts at absolute zero, which is 0 K. It does not have negative values.

2. **Understanding Absolute Zero**:
- Absolute zero is the theoretical temperature at which particles have minimum thermal motion. In the Kelvin scale, this is defined as 0 K.
