Absolute Zero

Real World Example

Imagine trying to squeeze the very last bit of toothpaste from a nearly empty tube, no matter how hard you press, nothing more comes out. This is similar to the concept of absolute zero, where it's the point at which molecules have been slowed down as much as possible, and no more energy can be extracted from them. Just like how there’s a limit to how much toothpaste you can get from the tube, at absolute zero, there’s a limit to how much you can slow down molecular motion, as it represents the lowest energy state possible.
