What is the absolute zero on the Kelvin scale according to the material?

Explanation:
Absolute zero is the temperature at which there is essentially no thermal energy left in a system, so molecular motion is minimized. The Kelvin scale sets this limit at 0 kelvin by definition, and it doesn’t use negative values. That’s why the absolute zero on the Kelvin scale corresponds to about -273.15°C and -459.67°F. It’s a theoretical limit that we can approach but never actually reach in practice.
