Combined Gas Equation
The equation which combines both Boyle’s law and Charle’s law is called combined gas equation.
According to Boyle’s Law V α 1/P
According to Charle’s Law V α T
By combining these two laws we get,
V α 1/P x T
V = a constant x 1/P x T
.·. PV/T = a constant.
P1 V1 / T1 = P2 V2 / T2.
If the pressure, volume and temperature of a fixed mass of gas are changed from P1, V1 and T1 to P2, V2 and T2 respectively
This equation is known as Combined gas equation.
