Graham's gas law formula
WebThe answer is False. If you solve the Ideal Gas equation for n (the number of particles expressed as moles) you get: n = PV/RT. Thus, at STP, the same volume of all gases have the same number of molecules (provided the conditions are suitable for the Ideal Gas Law to apply). A more dense gas has more MASSIVE molecules, but the same number of ... WebFick's law describes the movement of particles over time. There are a few strategies for maximizing particle movement, such as minimizing the distance the particles have to travel, using smaller molecules, increasing pressure, and increasing surface area. Fick's law can be expressed as an equation, but it is sometimes written in different forms.
