The moment of inertia for CH4 can be calculated from the expression 2 8 3 I  mHR where R is the CH bond length (109 pm). Calculate the first 3 rotational energy levels for this molecule and indicate degeneracy of each rotational state.

24. a sports ball is inflated to an internal pressure of 1.85 atm at room temperature (25 °c). if the ball is then played with outside where the temperature is 7.5 °c, what will be the new pressure of the ball? assume the ball does not change in volume nor does any air leak from the ball a) 0.555 atm b) 1.74 atm c) 1.85 atm d) 1.97 atm
