WebMolecular Speed and Energy MGas molecules travel at a range of speeds —some molecules move much faster than others. MThe average speed of a gas depends on its molar mass—the lighter the mass, the faster the average speed. Molecular Speed and Energy MAverage speed can be defined several ways for molecules: M The most probable speed WebThe speed associated to a group of molecules in average. It is valid in ideal gas, where the molecules do not interact with each other. Average molecular speed = Square root (3 …
