I was reading about the Kinetic Theory of Gases and I came to know about This Particular equation which piqued my interest.
I know about the Ideal Gas Law which gives us $PV=nRT$.
But this one contained Boltzmann's Constant and it goes like this $PV=Nk_BT$ where $k_B$ is the Boltzmann constant and T the absolute temperature.
Could I get some insights to how was this form of Ideal Gas Law Derived? And how was the value of $k_B$ and $R$ determined ? Any help would be appreciated.
