Mercury is the only one in liquid state at room temperature and is used in thermometers because of its high coefficient of expansion. Hence, the slightest change in temperature is notable when it's used in a thermometer. In this video, we will cover: 1. Measuring Temperature 2. Thermometer 3. Clinical Thermometer 4. Construction of Thermometer 5. How to read a Thermometer? 6. Reading different Temperatures 7. Precautions while handling a thermometer 8. Laboratory Thermometer 9. Reading a Laboratory Thermometer 10. Precautions while handling a laboratory thermometer 12. Laboratory thermometer to measure body temperature 13. Why is mercury used in Thermometers?
