Chemists and Physicists working with [[gas]]es came to the realization that the conventional temperature scales were not adequate for characterizing the effect of temperature on the decrease in [[volume]] and [[pressure]] of gases with the corresponding decrease in the actual temperature of the gases.

Ultimately, they realized that if they could decrease the temperature of an ideal gas to a point where all [[molecular motion]] ceased, that would be a good "[[absolute zero]]" point. They found that this temperature would be -273.16 °C (-459.6 °F).
