What is absoulte zero?

Answer 1

Not a simple answer but here goes. Absolute zero is a temperature marked by a 0 entropy configuration. It is the coldest temperature theoretically possible and cannot be reached by artificial or natural means, because it is impossible to decouple a system fully from the rest of the universe. Absolute zero is defined as precisely 0 K on the Kelvin scale, which is a thermodynamic temperature scale, and −273.15 degrees on the Celsius scale.

Answer 2

Absolute zero is the lowest possible temperature, at which point molecules cease to move and all thermal energy is removed from a system. It is equal to 0 Kelvin, or approximately -273.15 degrees Celsius. At this temperature, all matter lacks any heat energy and cannot be further cooled.

Answer 3

Absolute Zero means zero degree kelvin which is equal to -273.15 degree Celsius in Celsius scale

Answer 4

When all motion on the molecular level stops. 247 degrees below zero or something like that number.

Answer 5

Absolute zero is defined as 0 degrees Kelvin which is -273.15 degrees Celsius.
