Key Stage 5

Meaning

Absolute temperature is the measure of temperature starting from absolute zero, typically measured in kelvins (K).

About Absolute Temperature

Absolute temperature uses the Kelvin scale, where 0 K represents absolute zero. Absolute zero is the point where a system has minimum internal energy. The Kelvin scale is an absolute thermodynamic temperature scale.

Examples

The temperature of liquid nitrogen is 77 K. Room temperature is approximately 293 K on the Kelvin scale.
