"absolute zero" or 0 degrees Kelvin.
Absolute Zero is a theoretical temperature where all molecular activity ceases and by international agreement it is set at -273.15 Celsius.
Because temperature is actually a measure of molecular/particle movement and absolute zero is where there is no movement at all.
Kelvin (K) is actually the same scale as Celsius (C), but whereas Celsius is set such that zero Celsius is the freezing point of water, the Kelvin scale is set such that zero Kelvin is absolute zero, which is the temperature at which all kinetic. Absolute zero is zero degrees Kelvin, at which point there is no kinetic activity in a molecule or atom. There are presently no theoretical means of achieving absolute zero.
Zero degrees Kelvin is the theoretical temperature at which all molecular motion stops. It is called Absolute Zero. It is equal to -459.4*F and -273*C
absolute zero
Absolute zero is the coldest theoretical temperature; the temperature at which all subatomic movement is zero.
Absolute zero is the (theoretical) limit at which all molecular movement stops (that means that the total kinetic energy of all the molecules in the substance being cooled to absolute zero becomes zero).

There is no theoretical upper limit for temperature.

Molecules are constantly in motion. Whether they are free moving, as in a gas, or are vibrating in place, as in a solid object, they still move. an object that has reached the theoretical temperature of absolute zero would have no molecular motion, but absolute zero is purely theoretical and is thereby unattainable.
Kelvin (K) is actually the same scale as Celsius (C), but whereas Celsius is set such that zero Celsius is the freezing point of water, the Kelvin scale is set such that zero Kelvin is absolute zero, which is the temperature at which all kinetic.

The Kelvin scale is based on the absolute motion of molecules, at absolute zero, there is no motion. Of course this is theoretical, it has never been reached, though we've come close, withen a few thousandths I think.
The lowest temperature is known as absolute zero which is equal to 0K (0 Kelvin) and -273.15 Celsius (-459.67F). Absolute zero has never been recorded but is the theoretical temperature of which no heat can be extracted from a system. It is theoretical because at 0K matter would have no pressure and therefore no volume.
