What is thermometers?
Verified Answer
What is thermometers?
A thermometer is an instrument we can use to measure temperature. An analog thermometer consists of a sealed tube with markings on it. These markings are increasing temperatures in Celsius or Fahrenheit. The markings on a clinical and weather thermometer are different, but they work in the same way.
The glass tube of a thermometer usually contains mercury. Mercury is perfect to test temperature because it changes from a solid to liquid very easily.

When the metal tip of the thermometer comes into contact with the material it is testing, it conducts heat energy to the mercury. The mercury turns into liquid and so it expands. It begins to rise up the tube. Where it stops, is where you can take the temperature reading on the scale.
