What is absolute zero?

Category: Science

Answer:

Absolute zero is the theoretical assumption of the lowest possible temperature. This assumption concludes that absolute zero is void of all thermal energy and according to the laws of thermodynamics, can’t be achieved. It is defined as 0 Kelvin (0 K) which is equivalent to approximately -273 C (273.15 C or -459.67 F). The lowest actual temperature ever recorded (in a lab) was 1/2 billionth of a degree above absolute zero.
