Question

Which of the following can be used to measure the temperature of boiling water?

• A. Clinical thermometer
• B. Laboratory thermometer
• C. Both laboratory and clinical thermometer
• D. Barometer

Answer 1

The correct option is B

Laboratory thermometer

Laboratory thermometers are used to measure temperatures or temperature changes with a high degree of precision. In Celsius scale, the temperature range of laboratory thermometers is from $-{10}^{\circ }C$ to ${110}^{\circ }C$. The boiling point of water lies within the range of a laboratory thermometer.
The range of clinical thermometer is between ${35}^{\circ }C$ to ${42}^{\circ }C$, therefore it cannot be used to measure boiling point of water.
The barometer is an instrument used to measure air pressure.
