P1B.1 A rotating slotted-disc apparatus consists of five coaxial 5.0 cm diameter discs separated by 1.0 cm, the radial slots being displaced by 2.0° between neighbours. The relative intensities, I, of the detected beam of Kr atoms for two different temperatures and at a series of rotation rates were as follows: v/Hz 20 40 80 100 120 I (40 K) 0.846 0.513 0.069 0.015 0.002 I (100 K) 0.592 0.485 0.217 0.119 0.057 Find the distributions of molecular velocities, f(v,), at these temperatures, and check that they conform to the theoretical prediction for a one-dimensional system for this low-pressure, collision-free system.

Vibrations of molecules can be approximated by a harmonic oscillator only near the mini- mum of the binding potential curve, i.e., for small amplitudes for vibrations. Much better description is provided by the Morse potential 2 1 -h?w² ( n+ 4De En = hw ( n + A) Consider the 39K 35C1 molecule. In the far infrared spectrum, it has an intense line at 278.0 cm-1. Assume that it is an ideal quantum harmonic oscillator and estimate the period of vibration of the molecule. B) Now consider that 39K 35C1 molecule is described with a Morse potential with De 34843.15 cm-1 (this value comes from an experimental fit from the literature). If the excitation from the vibrational ground state to the first excited state is 278.0 cm-1, how much would the period of vibration change? How much would the energy transition between the first and second excited vibrational level differ from 278.0 cm-1?

A capillary viscometer was used to measure the viscosity of a fluid at room temperature. At a pressure drop per unit length of 0.28 mmHg cm−1, i.e., ΔP/L, the measured flow rate of the fluid through the capillary viscometer was found to be 0.0125 cm3 s−1. When the value of ΔP/L was increased to 0.79 mmHg cm−1, the flow rate of the fluid was found to be .047 cm3 s−1. Under these conditions, is the fluid Newtonian or non-Newtonian? Be sure to justify your answer.
