Expert Answer
- Mercury is toxic, and it is very difficult to dispose it when the thermometer breaks.
- Hence, digital thermometers are used to measure the temperature.
- Digital thermometers use a computer chip/heat sensor to tell the temperature instead of mercury.
- The body whose temperature is to be measured is brought in contact with the thermometer and it recieves heat until it comes at a temperature equal to the temperature of the hot body.
- The sensor-chip mechanism within reads the temperature and displays the same on a small screen.
- Display screen commonly used these days is a light emitiing diode panel (LED)
