After Boyle’s Law was published by Robert Boyle in 1662, it was postulated by Jacques Charles in 1780 and confirmed in 1802 that the volume of a given mass of a gas would vary according to the absolute temperature of the gas. At this time, no one knew the true nature of gases. #Charles’s Law states that under the condition of constant pressure the volume of a given mass of an ideal gas is directly proportional to its absolute temperature. Put into a mathematical form, Charles’s Law becomes Equation 4.6.

About 2nd graph
Amazingly the lines of the graph all converged on a single point. As the volume of the gas cannot be negative, we can’t go beyond this point. The graph suggests that Charles’ Law does not work at temperatures lower than this. We now know the reason for this: the lines converged on absolute zero and there are no temperatures below this temperature!
That’s worth repeating: there are no temperatures below -273.15°C. There is something fundamental in the laws of physics that means this temperature is a lower limit.
