Have you heard about infrared thermography? Thermal images allow you “seeing” the heat that is given off by different objects. Let’s count the heat of everyday objects that are used in every household. How do we count the heat? Temperature is shown by colors. The warmest color is white. Then goes yellow, orange, red and purple. The coldest color is black.
