Academics

1. Extend the considerations of microscopic and macroscopic nonequilibrium and equilibrium of isolated and interacting-contacting material bodies given in this section to an everyday environment or situation, and to the universe.

2. What is the de Broglie wavelength of an electron at the average kinetic energy k_BT at T=300K? [Why not (3/2)k_BT?] This is known as the thermal de Broglie wavelength of an electron.

How many valence electrons are there in a thermal de Broglie cube of Si whose edge is the thermal de Broglie wavelength?

What is the fluctuation in electron number in such a cube? What is the significance of localization of an electron by a wave packet in a thermal de Broglie cube?
