Jul 3, 2024 · The formula for calculating the diffusion rate of a second gas based on the diffusion rate of a first gas and their molar masses is given by: \[ R2 = \frac{R1}{\sqrt{\frac{M2}{M1}}} \] where: \(R2\) is the diffusion rate of gas 2, \(R1\) is the diffusion rate of gas 1, \(M2\) is the molar mass of gas 2, \(M1\) is the molar mass of gas 1.
3 days ago · The heat equation governs heat diffusion, as well as other diffusive processes, such as particle diffusion or the propagation of action potential in nerve cells. Although they are not diffusive in nature, some quantum mechanics problems are also governed by a mathematical analog of the heat equation (see below).
