Kelvin

Kelvin is a temperature scale used mainly by scientists that starts from absolute zero, the point where particles have minimal motion. Absolute zero is at 0 K and is equivalent to -273.15°C. Unlike Celsius or Fahrenheit, Kelvin has no degrees below zero, making it ideal for precise scientific measurements of temperature and energy. As temperature increases in Kelvin, so does the energy and activity of particles. This scale helps us understand phenomena at very low temperatures, such as in physics and chemistry, providing a universal standard that is directly related to energy levels in matter.
