Temperature measures the average speed of molecules in a body of matter by measuring how fast molecules are moving around in an object. The faster the molecules are moving, the hotter the object is.
The slower the molecules are moving, the colder the object is.
There are two ways to measure temperature; one is in Fahrenheit and the other is in Celsius. Most countries measure in Celsius but the United States of America is one
of the few countries to measure in Fahrenheit. The red liquid in thermometers
is usually alcohol because mercury, which was used in the past, is a dangerous subtance.Temperature is a measurement that is important for knowing how materials or life will respond.
