The Absolute Zero is when particles will have 0 energy to even vibrate or move regardless of any substances.

The Kelvin Scale's zero = Absolute zero (-273 degrees celsius), and scientists want to base their temperature scale at the very, very start.

Nonetheless, many of the negative temperatures on the Fahrenheit scale and the Celsius scale would be converted to positive values on the Kelvin scale. Which would be easier to use for calculations in science.

Kelvin scale is applied to all in chemistry and it is the main temperature scale in the science community.
