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.
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.
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.
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.
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.
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.

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.
The digital thermometer is less acurrate then the basal digital thermometer. they use different methods of working. iter than that there is no difference.
Mercury expand more easily.so it need large space
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.
An Alcohol thermometer would be the best as it is more sensitive than the mercury thermometer.

Because mercury is very fast dissolving metal
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.

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.
