Mercury thermometers have been used for centuries to measure temperature, and they are still popular today due to their accuracy and durability. However, many people don't know much about how these thermometers work or how to use them properly. In this complete guide to mercury thermometers, we'll cover everything you need to know to use these tools effectively and safely.
How Mercury Thermometers Work
A mercury thermometer is a type of liquid-in-glass thermometer that uses mercury as the liquid. The thermometer has a small bulb at the end that is filled with mercury. When the temperature changes, the mercury expands or contracts, causing the level of mercury in the thermometer to rise or fall. The temperature is then read by looking at the markings on the glass tube.
Mercury thermometers are very accurate because mercury expands and contracts at a consistent rate when the temperature changes. This means that a small change in temperature will cause a large change in the level of mercury, making it easy to read the temperature.
How to Use a Mercury Thermometer
Using a mercury thermometer is relatively simple, but there are some steps you should follow to ensure accurate readings.
- Make sure the thermometer is at room temperature before using it. If it has been stored in a cold or warm place, the mercury may not be at the right level, leading to inaccurate readings.
- Shake the thermometer down before using it. This will ensure that the mercury is at the bottom of the glass tube and ready to measure the temperature.
- Place the thermometer in the location where you want to measure the temperature. For example, if you want to measure body temperature, place the thermometer under the arm or in the mouth.
- Wait a few minutes for the mercury to adjust to the temperature. This will ensure an accurate reading.
- Read the temperature at the top of the mercury column. This is the most accurate reading.
Safety Precautions
While mercury thermometers are generally safe to use, there are some safety precautions you should take to avoid exposure to mercury.
- Never break a mercury thermometer. If the thermometer breaks, clean up the mercury immediately and follow proper disposal procedures.
- Keep mercury thermometers out of reach of children. Mercury can be harmful if swallowed.
- Do not use mercury thermometers for oral temperature measurement in infants and young children.
- Follow proper disposal procedures for mercury thermometers. Many states have laws regarding the disposal of mercury thermometers, so be sure to check local regulations.
FAQs
Q: Are mercury thermometers accurate?
