do you know the formula which relates the given terms

2. rvc

PV= nRT do you know this?

Since pressure and temperature are constant and also the gas constant R is a constant by itself so the volume is directly proportional to the number of moles.

5. anonymous

also known as Boyle's Law

@clashae please reply

i forgot the choices \

You can just use the formula and manipulate the variables and the see the relationship between them as opposed to just memorizing the laws

9. Photon336

PV = nRT Both T and pressure are constant. Look at the formula, the two terms that are on the same side P and V are inversely proportional Pressure, temperature volume and temperature are proportional to one another. You don't really need to memorize the laws because the gas laws are derived from this equation.

10. Photon336

You find that Volume is proportional to # of moles.

huh ? @photon336

@clashae I posted earlier in the reply, something you should probably focus on is manipulating the ideal gas equation and understanding, how the variables are related when you keep one or more constant. Because all the gas laws such as Ie boyles law etc.. You can derive from the ideal gas law pV =nRT. Ie like if you keep T constant and want to study the pressure and volume your formula becomes P1V1 = P2V2. Which implies that they are inversely proportional.
