The gas laws, collectively, are a series of observations explaining the response of the gaseous state of matter to changes In the physical surroundings of the gas. One of these physical variables, temperature, Is
quantified by CHARLES' LAW. Simply put Charles' Law states that an Ideal Gas decreases and increases In volume with a corresponding decrease or increase in temperature. Further, Charles' Law quantifies this
statement by stating that the Ideal Gas will respond to the change in temperature by increasing or decreasing the initial volume by 1/273 of the original volume for each degree Celsius change in temperature.
If we extend Charles Law to its logical end, at extremely low temperatures, the Ideal Gas should disappear completely. With a real gas the situation is different. In actuality, a real gas would change PHASE or
liquify long before the theoretical limit of contraction. This theoretical limit Is called ABSOLUTE ZERO. Using a real gas, air, and the general CHARLES' LAW relationship, It is possible to estimate the point of
ABSOLUTE ZERO.
