absolute zero

I’m certainly no scientist, which is why I am a member of Quora and subscribe to Silk Road. He explains things so clearly. He states:
Absolute zero is the lowest possible temperature in the universe. It’s defined as zero kelvin (-273.15 degrees Celsius, -459.67 degrees Fahrenheit).
At this point, atoms and molecules have no kinetic energy, meaning they can’t vibrate or move around.

They’re basically frozen in place.

But here’s the thing: absolute zero is impossible to reach in practice. Why? Because of the laws of thermodynamics, that’s why.

• The first law says that energy can’t be created or destroyed, only transformed.
• The second law says that entropy, or disorder, always increases in an isolated (closed) system.
• The third law says that entropy approaches a constant value as temperature approaches absolute zero.

If we cool something down to absolute zero, we need to remove all the heat from it, but heat is a form of energy, and you can’t get rid of it completely. You can only transfer it somewhere else, and as you do that, you increase the entropy of the system, making it harder to reach the lowest possible entropy state.
