Absolute Zero

Absolute zero is the lowest possible temperature, measured at 0 Kelvin or -273.15°C. At this point, particles reach their minimum energy state, virtually stopping their random motion. Although it cannot be practically reached, scientists can get very close to this temperature in laboratory conditions. Absolute zero is fundamental in thermodynamics, providing a baseline for temperature measurements and helping us understand the behavior of matter at extremely cold conditions, such as in cryogenics and quantum physics.
