Absolute zero and the Kelvin scale

Much of physics and physical chemistry is based on the Kelvin temperature scale, which begins at absolute zero. Absolute zero is the coldest possible temperature. Therefore, there is no temperature lower than OK. Notice that it is not zero 

As an example, what is body temperature (98.6°F) on the Kelvin scale  

We don t have an equation to convert between K and °F. It would be a waste of time for you memorize one, because we can simply use the two relationships we already know. First, let s convert 98.6°F into degrees Celsius  

Then we use the second relationship to convert °C into kelvins  

you should be able to confirm that absolute zero is equivalent to -459.67°F

Kelvin, theorized that extremely cold temperatures could stop the motion of atoms and molecules. This became known as absolute zero, and the Kelvin scale of temperature measurement emerged.
