Question: b experimentally a situation close to the random mixture case...

Question details

b) Experimentally, a situation close to the random mixture case can be obtained by vig- [6] orously shaking the box. On the other hand, a well-mixed state can be de-mixed by gentler shaking. Explain qualitatively how potential and kinetic energy and entropy change when the system is shaken slowly or rapidly, respectively c Define the granular temperature of the vibrated powder by analogy with the mean- [2] ing of temperature in the kinetic theory of gases.
