What are temperature scales explain how Celsius and Fahrenheit scales are defined?
Temperature is a measure of the average kinetic energy of the particles in matter. The Fahrenheit scale defines the freezing point of water as 32°F and the boiling point as 212°F. The Celsius scale sets the freezing point and boiling point of water at 0°C and 100°C respectively.
What are the three main temperature scales used and how are they different from each other?
There are three main scales commonly used in the world today to measure temperature: the Fahrenheit (°F) scale, the Celsius (°C) scale, and the Kelvin (K) scale. Each of these scales uses a different set of divisions based on different reference points, as described in detail below.
