What is Temperature?

The word "temperature" is defined as the level of hotness or coldness that an environment or a body has. Temperature is measured with the use of a tool called a thermometer. The normal temperature of a human body is said to be 98.6 F or 37.0 C. Depending on how the word "temperature" is used, it can also mean a rather high degree of body heat that is being caused by an illness or a fever, which is used in the phrase "having a temperature" or having a fever.

What is a Thermometer?

A thermometer is a device that is used to measure the temperature of a living organism, a place, or an object. The word "thermometer" comes from two words, which are "thermo", a Greek word meaning "heat", and "meter" which means "to measure". The thermometer uses two different scales to measure heat, which are the Celsius, and the Fahrenheit scales. Celsius can be converted to Fahrenheit and vice versa with the use of a converter or a temperature calculator. For the Fahrenheit scale, the freezing point is at 32 F, while the Celsius scale has it at 0 C. Boiling point for Fahrenheit is at 212 F, and for Celsius, it is at 100 C. You can convert Fahrenheit to Celsius and vice versa with the conversion rate of 33.8 F = 1 C.

How does a thermometer work and who invented it?

No single person was credited with the invention of the thermometer, but a lot of people had contributed to its development, including Santorio Santorio, Galileo Galilei, Cornelius Drebbel, and Robert Fludd. When you are tasked to read a thermometer, you will need to look at the silver or the red line inside the tube, and you will be able to read the Celsius and Fahrenheit readings of the temperature by looking at the level where the line stops.

Kinetic Theory

Also called the collision theory and the kinetic-molecular theory, this theory states that the temperatures, pressures, or volumes of different gases can be determined by considering their motion and molecular compositions.


This is defined as the physics that takes care of the conversions and relationships between heat and other energies. This can also be described as the study of laws that cover the conversion of energy into different forms. Temperature is not only a measurement for heat. It also relates to laws of physics and theories on how heat is transferred and converted from one form to another.
