Question

All liquids cannot be used in thermometer
Why?​

Answer 1

Explanation:

here's your answer

• Most metals are good conductors of heat and they are solids at room temperature. Mercury is the only one in liquid state at room temperature. It's used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it's used in a thermometer.

Answer 2

All liquids cannot be used in thermometers because:

- Liquids may stick to the wall of the thermometer so measurement can become difficult

- Many of them may be volatile.

- Some liquids are very strong and reactive.

- As their expansions are not like mercury.

- These might not be a good conductor of heat.
