Combined Someone took all of those laws, and just made them into one. Why? because they were lazy and didnt want to remember them all. Good enough for me, lets learn it.

if PV1=PV2 and P/T1=P/T2 and V/T1=V/T2

well, we can derive a pretty obvious equation out of that

the only thing different in the second two is one variable is missing, and they are divided by temperature.

so why dont we just add the missing variable?

PV/T1=PV/T2

Which is the combined gas law.

easy right, knowing this means three equations are now useless.

lets try one 1atm*1L/1K=5atm*.2L/1K

In this case when P went up, V went down.

But if P goes up, T can also increase as its dividing P. so..

P increase= lower V OR higher T

V increase= lower V OR higher T

T increase= Higher V OR Higher P.

Not that tough. [|back]
