Up to this day, the race to the absolute zero is still incomplete. Mankind has not yet succeeded in achieving the lowest possible temperature there is. You must be wondering on why scientists know about this absolute zero when no one has ever conquer it yet. Let us define absolute zero. Accordingly, it is a temperature that no known system can still engage in heat transfer. It is a state wherein the molecules of a matter have stopped moving. It is the coldest of the coldest. It is comparable to -273.15 degrees on Celsius or -459.67 degrees on Fahrenheit scale.
Matters with absolute zero temperature exhibit superconductivity and superliquidity. An object which is an insulator in a normal room temperature can conduct electricity the nearer it gets to absolute zero. The lowest temperature ever reached in a lab happened in Helsinki University of Technology on 2000. It was 100 pK (1×10−10K). Pleas note that 0 Kelvin is also known as the absolute zero.
Science is a continuing study. Someday and somehow, someone will accomplish this goal to reach the absolute zero.
