During hibernation, an animal’s metabolism slows down, and its body temperature lowers. For example, a California ground squirrel’s body temperature lowers from 40.0°C to 18.5°C during hibernation. If we assume that the air in the squirrel’s lungs is 75.0% N2 and 25.0% O2, by how much will the rms speed of the air molecules in the lungs have decreased during hibernation? Boltzmann's constant is 1.38 × 10−23 J/K. Molar mass of Nitrogen is 14.00674 u and Oxygen is 15.9994 u.
