A thermometer is a device used to measure temperature and can be either digital or analog. They typically contain a temperature-sensing element, such as Mercury or a thermocouple, that expands or contracts based on temperature changes. Thermometers are calibrated to provide accurate temperature readings in various units, such as Celsius or Fahrenheit.

How do you tell how hot or cold something is?
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
What are interesting facts about the thermometer?
The first modern thermometer was invented by Galileo in the early 17th century. The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit in the early 18th century. The Celsius scale was developed in the mid-18th century by Anders Celsius.
What is the plural of thermometer?

What do you call an ear thermometer?
An ear thermometer is commonly referred to as a tympanic thermometer.
What is a glass bulb of a thermometer?
A glass bulb of a thermometer is the part at the bottom of the thermometer that contains mercury or colored alcohol that expands and contracts with temperature changes. This expansion and contraction of the liquid is what causes the thermometer to measure and display the temperature.
What are facts about thermometers?
galileo invented it
