absolute temperature

Absolute temperature is a measurement of how hot or cold something is, based on a scientific scale called Kelvin. Unlike Celsius or Fahrenheit, which are based on water's freezing and boiling points, Kelvin starts at absolute zero—the lowest possible temperature where atoms stop moving. At this point, particles have minimal energy. As temperature increases in Kelvin, particles move more actively. Absolute temperature provides a uniform, scientific way to measure thermal energy, essential for understanding physical processes, scientific experiments, and thermodynamics. It’s a neutral, fundamental scale that accurately reflects the energy state of matter.
