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
