The Kelvin Scale
The Kelvin scale is a temperature scale that is commonly used in science.
The Kelvin scale
- The Kelvin scale is an absolute temperature scale defined to have 0 K at the lowest possible temperature, called absolute zero.
Absolute zero
- Absolute zero (0 K) is the lowest possible temperature.
- At absolute zero, there is no temperature.
- This means that there is no kinetic energy or vibration of molecules.
Converting from degrees to Kelvin
- To find degrees from Kelvin, just add 273.15.
- E.g. 0oC = 273.15 K.
- E.g. Water boils at 373.15 K.
