Absolute Zero
What is it?
Absolute zero is the temperature at which no known system can still engage in heat transfer. Absolute zero is the temperature where all molecular motion ceases.
On a Kelvin thermometer, absolute zero is simply "zero." On a Celsius thermometer, absolute zero is at -273 degrees. Absolute zero is the lowest temperature in the world, and has never actually been attained in a laboratory.
Give me an example!
When you freeze water into ice, the molecules form a solid crystalline structure and move much less than when the water is in its liquid phase. If you continue to lower the temperature of the ice, you will reach a point where all molecular motion comes to a standstill - theoretically, at absolute zero.
