Unformatted text preview: oxygen , not for nitrogen! Additional part: Calculate the rms angular velocity (in radians per second) of an oxygen molecule at room temperature. Directions: Use the equipartition formula I ω 2 x / 2 = kT/ 2. To calculate the moment of inertia I , use the distance d = 1 . 21 × 10-10 m between the oxygen atoms in O 2 . 4. Problem 1.21, 5 points. Pressure from hail. Assume that collisions of hailstones with the window pane are elastic. 5. Problem 1.24, 5 points. Thermal energy of aluminum .
