-This empirical relation was first suggested by the French physicist Jacques-Alexandre-César (J.-A.-C.) Charles about 1787 and was later placed on a sound empirical footing by the chemist Joseph-Louis Gay-Lussac.
Charles’ Law
a statement that the volume (V) occupied by a fixed amount of gas is directly proportional to its absolute temperature (T), if the pressure remains constant.
Charles’ Law
The graph of Charles's law is a volume-temperature graph. And it is as follows: The plot in the volume vs temperature (in K) graph is a _____ passing through the origin. The above graph is a volume vs temperature graph plotted as a constant pressure for a fixed amount of gas.
Straight line
The equation of Charles's law is
V = kT.
When the pressure is constant this equation is used to compare different conditions on the same substance
V1/T1 = V2/T2
Temperature is directly proportional to volume
T ∝ V
Volume divided by temperature is equals the K constant
V/T = k
