New Arctic Lakes Could Soon Be a Major Source of Atmospheric Methane
For centuries, a massive store of carbon has been locked underground in the Arctic's permanently frozen soil known as permafrost. As Earth's climate continues to warm, that carbon has begun to leach into the atmosphere, the result of...

Practice Problem: Molar Mass of a Gas
We know about the ideal gas law, but what are some clever things we can do with it? Well, how about identifying an unknown gas by solving for its molar mass? Sure, why not!
Professor Dave Explains
Practice Problem: Graham's Law of Effusion
We know that molecules will travel at an average velocity that is inversely proportional to their molar mass. This means that lighter gases travel faster. We can relate the rates of effusion for two gases using Graham's law, and we can...
