Question

Consider two equal-sized containers, one filled with H2 gas and one with O2 gas at the same temperature and?and pressure. The average velocity of the O2 molecules is (equal to, greaterthan, less than) that of the H2 molecules.1. greater than2. equal to3. less than

Answer 1

The average velocity of the O2 molecules is less than that of the H2 molecules because O2 molecules have a greater molar mass.

Step-by-step explanation:

The average velocity of the O2 molecules is less than that of the H2 molecules. This is because the average speed of gas molecules is inversely proportional to the square root of their molar mass. Since O2 molecules have a greater molar mass than H2 molecules, they have a lower average velocity.
