nollakelvin

nollakelvin is a term that refers to absolute zero, the theoretical lowest possible temperature. At absolute zero, particles have minimal vibrational motion, meaning they are at their lowest energy state. This temperature is defined as 0 Kelvin (K) on the Kelvin scale, which is an absolute thermodynamic temperature scale. It is equivalent to -273.15 degrees Celsius (°C) or -459.67 degrees Fahrenheit (°F).

Reaching absolute zero is practically impossible according to the third law of thermodynamics, which states that it is impossible to reach absolute zero in a finite number of steps. While scientists have achieved temperatures extremely close to absolute zero in laboratories, they have never been able to reach it exactly. At temperatures near absolute zero, matter exhibits unusual quantum mechanical properties, such as superconductivity and superfluidity. These phenomena are areas of active research in physics. The concept of absolute zero is fundamental in thermodynamics and statistical mechanics.
