Digital thermometers are preferred over Mercury thermometers because they are more accurate, faster, and safer to use. Digital thermometers provide a digital reading, eliminating the risk of parallax error associated with reading a mercury level. Additionally, digital thermometers do not contain mercury, making them safer for the environment and in case of accidental breakage.

What is the diffrerence between digital thermometer and mercury thermometer?

A digital thermometer uses electronic sensors to measure temperature and displays the reading digitally, while a mercury thermometer uses a column of mercury to measure temperature and has a calibrated scale to indicate the temperature. Digital thermometers are often faster and more accurate than mercury thermometers, and are also safer since they do not contain mercury.


Is a mercury thermometer an analog device?

Yes, a mercury thermometer is an analog device because it measures temperature using a column of mercury that expands and contracts based on the temperature changes. This movement is then read on a scale to determine the temperature.


How is digital thermometer is better than conventional thermometers?

Digital thermometers have the advantage that they are simpler to read and the electrical components used to make them are cheap, accurate, and reliable. An analog thermometer may have ambiguity when you read it because of angle of viewing, difficulty seeing, or many other things while a digital thermometer clearly outputs a single unambiguous number.


How cold would it have to be in order to freeze a mercury thermometer?

Mercury freezes at -38.83°C (-37.89°F). In order to freeze a mercury thermometer, the temperature would have to be lower than this point. However, prolonged exposure to temperatures below freezing may damage the thermometer.


Do pool thermometers contain mercury?

Some pool thermometers do contain mercury, but there are alternatives available that use different substances like alcohol or digital sensors. If you are concerned about the presence of mercury in a pool thermometer, look for options that explicitly state they are mercury-free.

Would ethanol be better than mercury for an outdoor thermometer in the arctic?

Ethanol would be better than mercury for an outdoor thermometer in the Arctic because ethanol has a lower freezing point than mercury, making it more reliable in extremely cold temperatures. Additionally, ethanol is less toxic than mercury, which is important for environmental and safety reasons in outdoor settings.


What is the difference between a digital and a basal digital thermometer for taking temperatures?

The digital thermometer is less acurrate then the basal digital thermometer. they use different methods of working. iter than that there is no difference.


Why is the clinical thermometer shorter than the mercury thermometer?

Mercury expand more easily.so it need large space


Mention any two points of difference between a clinical thermometer and an ordinary mercury thermometer?

A clinical thermometer will offer more precise calibrated readings than a mercury thermometer. The range of measurable temperature differs between a clinical and a mercury thermometer with the mercury thermometer having the wider range.


Which thermometr will you take when you go to south expedition mercury or alchol?

An Alcohol thermometer would be the best as it is more sensitive than the mercury thermometer.

Why mercury thermometer is accurate than others?

Because mercury is very fast dissolving metal


How long should you keep the thermometer under your tongue?

You must hold your mouth closed and keep the thermometer in place for a certain period of time. If you have a digital thermometer, it will tell you when it's "done". If you are using an old "mercury thermometer", the thermometer must stay under the tongue for at least a minute to 2 minutes.NOTE: Mercury thermometers are being phased out. The mercury inside is highly toxic and you should dispose of all mercury thermometers by taking them to a recycling center that handles that. DO NOT THROW IT IN THE TRASH. Mercury is poisonous to every living thing.UPDATE: GERATHERM offers MERCURY FREE thermometers that work the same as the mercury ones. They are supposed to be safe.

Why does the mercury in the thermometer not spill even by moving it?

If the question relates to the tendency of the mercury to stay clumped together rather than separate inside the thermometer, it's due to the high surface tension of that element. Mercury can separate inside the thermometer, but its unusual for it to do that for the stated reason.
