Development of the Kelvin Absolute Temperature Scale •William Thomson (later Lord Kelvin) was interested in Charles’s Law which states that when a gas is cooled by one degree Celsius, it’s volume drops by 1/273 –This would lead to zero volume at -273°C –How can matter exist without taking up space? •Thomson instead suggested that it was the energy of motion that decreased with temperature – At -273°C, the molecules cease motion and essentially not take up space –He called -273°C absolute zero because no further temperature reduction is possible. This later became known as 0 Kelvin.
