| [...]: movement of gases through a tiny pore or opening | show 🗑
|

| show | HS Chemistry courses love the word effusion, but it really just means diffusing out of an opening.
🗑

| show | Graham's law of effusion: The rate of effusion is inversely proportional to the square root of the molar mass of the gas particles.
🗑

| show | Notice that in Graham's law, gas 1 is on top on the left, but on bottom on the right.
🗑

| Although Graham's law describes *effusion* rates, it can also be used to describe *[...] rates* and sometimes test-writers throw *[...] rate* questions at you and expect you to know that Graham's law relates to both. | show 🗑
|
||||
| Graham's law is used for BOTH effusion and [...] rate problems, even though his law is called Graham's law of *effusion*. | show 🗑
