What is absoulet zero?:
the theoretical temperature at which there is no heat or motion, and is the lowest possible temperature in the universe:
Temperature: Absolute zero is 0 kelvin, or -273.15° Celsius, or -459.67° Fahrenheit
Explanation: At absolute zero, the atoms and molecules in a substance have minimal kinetic energy, meaning there is almost no thermal motion
Absolute zero is determined by extrapolating the ideal gas law. The value of absolute zero was estimated over time, with Jacques Charles and Joseph Louis Gay-Lussac estimating it to be -273° Celsius in the 18th century. In the first half of the 20th century, researchers around the world worked to determine the last two digits of absolute zero, with researchers at Tokyo Institute of Technology ultimately settling the dispute.
