In reference to your statement about the enclosed charge equaling zero telling you nothing about the \vec E field, that's false. It tells you that \vec E = 0. Gauss' Law allows you to determine electric fields for regions. If you want to know the field in a particular region, the Gaussian...
Gauss' Law in it's mathematical form is \oint\vec E \cdot \vec {da} = \dfrac{1}{\epsilon _o}Q_{enc}. If we draw a Gaussian surface encompassing the region in which we seek to determine the electric field, the left side of the equation 'picks out' the all sources in this region, and says that...
Firstly, congratulations. Secondly, do well early, and do well consistently. Don't shrug off gen-eds or introductory physics courses as you're going to want to look as good as possible to grad schools. When you get into your later years, embrace the idea of independent research. Also, try to...
Some configuration in which none of the molecules "contact" the gap in the insulating wall after the transfer of high/low kinetic energy molecules.
I understand the low probability of such a configuration considering intermolecular collisions or forces. But does a non-zero probability have...
In regards to "Maxwell's Demon"
In regards to the Maxwell's Demon thought experiment and violation of the Second Law of Thermodynamics, I have a scenario that results in (a) question(s).
First I won't pretend to have extensive knowledge of Thermodynamics so bear with me...
Say we have two...
