Which of the following is the correct mathematical representation of Charles's law?
"The volume of a given mass of gas at constant pressure is directly proportional to its temperature on the Kelvin scale."
Let V1 be the volume of a certain mass of gas at temperature T1 and pressure, P. If the temperature is changed to T2, while keeping the pressure constant, its volume changes to V2 . The relationship among the four variables V1 , T1 ,V2 , and T2 is as follows:
V1T1=V2T2 (Pressure and mass constant)
