Kelvin Scale

Real World Example

Imagine trying to get the last bit of toothpaste out of a nearly empty tube. Just like there's a point where no more toothpaste can be squeezed out, in the Kelvin scale, there's a point called absolute zero where no more energy can be removed from matter. The struggle to extract the very last drop of toothpaste mirrors the concept of reaching absolute zero, where just as no more toothpaste can be squeezed out, no more thermal energy can be extracted from a substance.
