Do Mercury Thermometers Go Bad?

Yes, mercury thermometers can go bad. If the thermometer is exposed to extreme temperatures, the mercury can expand and contract, causing the glass to break. Also, if the thermometer is dropped, it can break and release the mercury inside.

Why Can't You Bring Mercury Thermometers on Planes?

While mercury thermometers are generally very accurate, over time they can become less so. This is because the mercury in the thermometer can evaporate, meaning that the readings will be lower than they should be. If you suspect that your mercury thermometer may be inaccurate, it’s best to get a new one.

Child Swallowed Mercury from Thermometer

Recently, there was a report of a child who swallowed mercury from a thermometer. This is a serious health concern because mercury is a toxic substance. If you think your child may have swallowed mercury, it is important to seek medical attention immediately.

Symptoms of mercury poisoning can include: headaches, dizziness, nausea and vomiting, diarrhea, abdominal pain, kidney damage, and neurological problems. In severe cases, mercury poisoning can lead to death. If you have any old thermometers in your home that contain mercury, it is important to dispose of them properly.

You can contact your local hazardous waste disposal site for information on how to do this.

Is It Safe to Use an Old Mercury Thermometer?

Old mercury thermometers are not safe to use. The mercury inside the thermometer can break open and release poisonous vapors into the air. If you breathe in these vapors, they can damage your lungs and nervous system.

Mercury is also a environmental pollutant, so it’s best to avoid using any products that contain it.

Can Mercury Thermometer Show Wrong Temperature?

Using a mercury thermometer to measure temperature is generally considered accurate. However, there are a few potential sources of error that could cause the mercury thermometer to show a wrong temperature.

One source of error is if the mercury thermometer is not properly calibrated.

If the thermometer is not calibrated, it may not show the correct temperature. Another source of error is if the mercury in the thermometer freezes. This can happen if the thermometer is exposed to cold temperatures for too long.

When this happens, the mercury will no longer be able to expand and contract properly, and as a result, it will no longer be able to give an accurate reading. Finally, if the glass tube of the mercury thermometer breaks, this can also cause errors in readings. If any of these factors occur, it is possible for a mercury thermometer to show a wrong temperature.

How Do I Know If My Thermometer is Bad?

If your thermometer is displaying a temperature that seems off, or if it isn’t working at all, it might be time to check if it’s accurate. Here are a few ways to test your thermometer: The boiling water test: Fill a pot with water and place your thermometer in the water.

If the thermometer is working properly, it should register 212 degrees Fahrenheit (100 degrees Celsius) at sea level. The ice water test: Fill a cup with ice and add cold water until it reaches the top of the ice. Again, place your thermometer in the cup and see what temperature it registers.

It should read 32 degrees Fahrenheit (0 degrees Celsius). If your thermometer passes both tests, then it is probably accurate. However, if it fails one or both tests, then you’ll need to get a new thermometer.

Conclusion

Mercury thermometers are one of the most popular types of thermometers, but many people don’t know that they can actually go bad. Mercury is a metal that is very sensitive to temperature changes, so it’s important to keep your mercury thermometer in a stable environment. If you’re not careful, your mercury thermometer can become inaccurate or even break.

Here are some tips for keeping your mercury thermometer in good condition:
