What is the difference between digital and mercury thermometer?
Digital thermometers measure electrical resistance and Mercury thermometers measure thermal expansion.
Two kinds of thermometer?

Mercury thermometer analog or digital device?
The traditional mercury thermometer has the mercury in a narrow glass tube with the readings/markings etched into the glass so it is neither analogue nor digital. I thought it was analogue.
The function of a Mercury thermometer?
to tell old people that have a mercury thermometer what the temperature is
Why water is not used in thermometer?
Well, Mercury can't freeze or evaporate at the temperature recorded on a standard thermometer. If water were used in a thermometer, we wouldn't be able to record any temperatures below its freezing point (0 degrees Celsius) or above its boiling point (100 degrees Celsius. Mercury has many unique properties. It is a liquid metal and as a metal it expands when heated. When the mercury is heated it rises in the thermometer. And markings on the glass indicate the temperature. Water does not do this. But now in this Digital World mercury has been loosing its importance just because everyone wants to use Digital Technology which provide fast and accurate reading and also safe in use, no doubt mercury provides an accurate reading of temperature but it is not fast and safe as compared to Digital Thermometer.
Does a mercury thermometer provide info in an analog or digital way?
Analog way. Unless you have a digital thermometer
What is a digital thermometer and is it made up of?
mercury
What is the difference between digital and mercury thermometer?
Digital thermometers measure electrical resistance and Mercury thermometers measure thermal expansion.
Does digital thermometers have mercury?
No. A digital thermometer works on a bi-metal usually

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.
How many minutes do you take a rectal temperature?
If using a mercury thermometer - about a minute. A digital thermometer - a few seconds.

Which thermometer is best for baby?
A digital thermometer is less 'intrusive' - as you don't need to hold it in place for any length of time (as you would with a mercury thermometer). Digital ones give you an almost instant reading.
How does a digital thermometer measure temperature if mercury is not present in it?
at its tip there is a thermistor which mearures temperature
Is a mercury thermometer an example of an analog or digital sensor?
analogue, since it doesn't use electronics
What is the difference between a rectal thermometer and an oral thermometer?
The tastes differ. An oral thermometer has a longer slender end that's inserted (into the mouth), compared to a rectal thermometer that has a short bulbous end inserted (into the rectum). The bulb reduces the chance of tearing the rectal wall, especially in infants. Some digital models have a setting for rectal vs. oral on the unit. The rectal temperature is known to be a little warmer and more accurate to body temperature. If you still have a glass and Mercury thermometer, be aware that mercury is a deadly toxin, and consider replacing the thermometer with a digital model.
