What Is It Used For?
A thermometer indicates how hot or cold something is.
-Doctors use it to measure patients’ body temperature.
-Thermometers are found in homes, schools, and weather stations.
-A person’s normal body temperature is usually between 36.5 and 37°C. If a thermometer shows a value above this range, it indicates a fever.
How Does It Work?
There are two types of thermometers:
Mercury Thermometer:
It contains a very thin glass tube filled with mercury, a silvery liquid. When the air or body temperature rises, the mercury expands and rises; when the temperature falls, the mercury contracts and drops.
Digital Thermometer:
It operates using electronic components and displays the temperature of the surface it touches as a number. Today, digital thermometers are used more frequently because they are faster and safer.
Where Is It Used?
-In hospitals: Doctors measure patients’ body temperature.
-At home: The temperature of children or adults is monitored.
-Outdoors: Air temperature is measured.
-In kitchens: The cooking temperature of certain foods is checked.
-In laboratories: Scientists track temperature changes during experiments.

History of the Thermometer
-The first concept of a thermometer was proposed in the 1600s by Galileo Galilei.
-The modern thermometer we use today was developed in 1714 by Daniel Gabriel Fahrenheit.
