Digital thermometers measure electrical resistance and Mercury thermometers measure thermal expansion.
Digital thermometers measure electrical resistance and Mercury thermometers measure thermal expansion.
Digital thremometer is shows digit and run by electric or cells mercury thermometer is shows mercury up and down. when temperature low and down.

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.
Laboratory thermometers can measure wide variety of temperature, whereas a clinical thermometer has a range between 95 to 105 Fahrenheit. Clinical thermometers are made to be used in a hospital to accurately determinebody temperature. They are often digital. Lab thermometers are made of metal or glass and usually don't give you an accurate reading as much as a "ball park". Clinical thermometer may have mercury but lab thermometers usually have alcohol .
to tell old people that have a mercury thermometer what the temperature is

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.

Analog way. Unless you have a digital thermometer
No. A digital thermometer works on a bi-metal usually
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.

If using a mercury thermometer - about a minute. A digital thermometer - a few seconds.

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.
There is no mechanical difference between a kelvin thermometer and any other kind so I think it would be the same as other thermometers i.e. Alcohol (because it is not as dangerous as mercury)
at its tip there is a thermistor which mearures temperature
