1. The problem statement, all variables and given/known data
i need to derive the ideal gas law

2. Relevant equations
this is the equation to end with.

PV=NkT

3. The attempt at a solution

I am not entirely sure where to start with this derivation. I believe newton laws.

where your gonna have Fx= Px/t

anyone guidance on where to get started on this equation.

Re: Derivation

I think you need to start with the gas laws stating that

$$\frac{P}{T}=Constant$$

$$\frac{V}{T}=constant$$

PV=constant.

Since the ideal gas law is a combination of those three laws.

Re: Derivation

would this be the constant called k...in the final equation.??

so P = Tk and V = Tk

Re: Derivation

Also you need to use Avogadro's law as well

try to prove that PV/T=C

Where C=V/n
