    Temperature
In summary, temperature is a measure of the average kinetic energy of particles in a substance, and it indicates how hot or cold something is. It should not be confused with heat, which is the transfer of thermal energy. Temperature is typically measured using a thermometer, and the most commonly used units are degrees Celsius and degrees Fahrenheit. Other factors such as altitude, humidity, and the type of thermometer can affect temperature measurements.

How hot something is?

A simple definition would be the amount of motion of atoms, a strict definition gets complicated.

What is temperature?

An object's temperature measures the average kinetic energy of its "jiggling" atoms or molecules. Average because some 'jiggle' fast and some 'jiggle' slow.
 

FAQ: Temperature: Definition & Measurement

What is temperature?

Temperature is a measure of the average kinetic energy of particles in a substance. In simpler terms, it is a measure of how hot or cold something is.

What is the difference between temperature and heat?

Temperature and heat are often used interchangeably, but they are not the same. Temperature is a measure of how hot or cold something is, while heat is the transfer of thermal energy from one object to another.

How is temperature measured?

Temperature is typically measured using a thermometer, which contains a liquid (usually mercury or alcohol) that expands or contracts when heated or cooled. The temperature is read based on the markings on the thermometer.

What units are used to measure temperature?

The most commonly used units to measure temperature are degrees Celsius (°C) and degrees Fahrenheit (°F). In scientific calculations, the Kelvin (K) scale is also used, where 0 K is absolute zero or the point at which all molecular motion stops.

What factors can affect temperature measurements?

There are several factors that can affect temperature measurements, including altitude, humidity, and the type of thermometer used. Additionally, human error can also play a role in inaccurate temperature readings.
