State some objections to using water-in-glass as a thermometer is mercury-in-glass an improvement

Explanation

### Step-by-Step Solution:

1. **Introduction to Thermometers**:
- Thermometers are instruments used to measure temperature. They typically consist of a liquid contained in a glass tube that expands or contracts with temperature changes.

2. **Objections to Using Water-in-Glass as a Thermometer**:
- **Low Boiling Point**: Water has a boiling point of 100°C. This means that it can only be used to measure temperatures up to this point. Beyond this temperature, water will turn into steam, making it unsuitable for higher temperature measurements.
- **Freezing Point**: Water freezes at 0°C. Below this temperature, water will turn into ice, which will not expand in the same way as liquid water, thus rendering the thermometer ineffective.
