Which equation agrees with the ideal gas law? mc005-1.jpg mc005-2.jpg mc005-3.jpg mc005-4.jpg
AlexFokin [52]
The ideal gas equation is pV = nRT


From that you can derive several equations, depending on which variables are fixed.


1) When n and T are fixed:

pV = nRT = constant


pV = constant => p1 V1 = p2 V2 => p1 / V2 = p2 / V1 ---> Boyle's Law


2) When n and V are constant:


p / T = nR/V = constant


p / T = constant => p1 / T1 = p2 / T2  ----> Gay - Lussac's Law


3) when n and p are constant


V / T = nR/p = constant   


V / T = constant => V1 / T1 = V2 / T2 ---> Charles' Law


4) When only n is constant


pV / T = nR = constant


pV / T = constant => p1 V1 / T1 = p2 V2 / T2 ----> Combined gas law.



There  you have the four equations that agree with the ideal gas law.
