Charles Law

This law was formulated by a Frenchman Jacque A.C. Charles in about 1787. It may stated in following two different forms:
 (1) "The volume of a given mass of a perfect gas varies directly as its absolute tempreture, whenthe absolute pressure remains constant.: Mathematically ,

                                          V / T = Constant
                                         V1/T1 = V2/T2 = V3/T3 = constant
(2) "All perfect gases change in volume by 1/273th of its original volume at 0degree C for every Idegree C in tempreture, when the pressure remains constant."
