Question

Why is mercury used widely in the thermometer ? Describe a thermometer with the help of diagram.

Answer 1

Mercury is widely used in thermometers because;

1. It's in liquid state at room temperature.
2. It has a high co-efficient of expansion, which means even the slightest change in temperature will make it move along the thermometer as per the temperature.
3. It also has a high boiling point which makes it suitable for measuring higher temperatures.
