| Title | Graham's Law of Effusion |
| Simulations | Sifati Gas |
| Keywords | Effusion, Kinetic-Theory of Gases, Graham's Law of Effusion, molar mass |
| Description | Students determine that the ratio of the rates of effusion and the average velocities of the particles of a mixture of heavy molecules and light molecules, at constant temperature,are the same. They use the ratio of the rates of effusion to determine the ratio of molar masses of the heavy (H) and light (H) molecules. |
