Which of the following gases would have the highest average speed at a given temperature?

Which of the following gases would have the highest average speed at a given temperature?

Step 1: Understand that gases consist of tiny particles that move around.
Step 2: Know that temperature affects the speed of gas particles; higher temperatures mean faster speeds.
Step 3: Recognize that lighter gases (like hydrogen) move faster than heavier gases (like oxygen or carbon dioxide) at the same temperature.
Step 4: Compare the molecular weights of the gases: hydrogen (H2) is lighter than oxygen (O2) and carbon dioxide (CO2).
Step 5: Conclude that hydrogen (H2) will have the highest average speed at a given temperature.
