13 Chemistry 1A F11 9.26.11 Dr. Shaka Course Code 40000 Charles’s Law • Jacques Charles (in France) found that for a given mass of gas and given pressure, that the volume was proportional to temperature. • A plot of volume versus temperature is thus a straight line (well above BP). • In 1848 Lord Kelvin realized that the lowest temperature attainable would then be when the gas appeared to have zero volume. This is absolute zero , 0 Kelvin.

15 Chemistry 1A F11 9.26.11 Dr. Shaka Course Code 40000 Charles’s Law • As volume is proportional to temperature, we can write V = k 2 T • If we know a ( V , T ) pair we know k 2 , and can calculate another ( V , T ) pair (for the same type of gas, same amount and same pressure). • The equation above is a precise formulation of Charles’s Law.
