Part II Graham's Law (average speed and molar mass) - Submicroscopic View Your observation 1. The speed of the particles is (circle one) a. Constant b. Variable C. same 2. The particles move in a between collisions. a. straight –line b. curved path 3. The speed of the particles changes following the collision with a. another particle b. the wall of the container c. both the wall of the container and another particle. Use the Track function explained earlier to help answer this question. 4. Collisions between particles or the walls of the container are elastic or not elastic. 5. The particles attractions to other particles. а. еxperience b. do not experience 6. The RMS speed of helium is as the mole of helium changes. a. constant b. variable 7. Record the RMS speeds of different gases in the following table. Table 1. RMS speed of gases Gas Не Ne Ar Molar mass g/mol RMS speed m/s 8. Is your observation of RMS speeds consistent the Graham's law of effusion, which states that rates of…
