Absolute Zero: The Quantum World Explored MANASA ARUN
The lower the temperature the more energy is required to remove heat from a substance, so, in order to achieve absolute zero, an infinite amount of work would be required; making absolute zero impossible to reach. Despite this, physicists have got as close as 38 trillionths of a kelvin above absolute zero (i.e., incredibly close!) at which point particles have very little kinetic energy.
Absolute zero, otherwise known as 0 kelvin or -273.15 degrees Celsius, is the lowest temperature theoretically possible and it is the temperature around which there is a multitude of unusual phenomena that could evolve our understanding of quantum mechanics. The only catch is that absolute zero is impossible to reach.
