How does n (number of moles) need to change to increase P (pressure) in PV = nRT?

Question

anonymous · Answer

Please try to rearrange the equation for n. Then try to figure out if P is directly or indirectly proportional to n.

anonymous · Answer

Well, you would need more moles, correct?  Because more moles would increase volume which also increases pressure?

anonymous · Answer

You were near to the answer. Can you explain how pressure and volume are related to each other? are they directly or indirectly proportional?

anonymous · Answer

it's directly proportional

anonymous · Answer

Let us consider a piston containing 10 L volume of gas at a Pressure of 1 atm. Let us increase the pressure. Would the volume increase or decrease?

anonymous · Answer

It should increase
