comment Why is SiO2 solid while CO2 is a gas?
CO2 is based on double-bonds, O=C=O. So the heart of the question is: "Why can carbon easily form strong double (and even triple) bonds, while silicon is barely capable of forming weak double bonds?"

comment Is Gauss' law valid for time-dependent electric fields?
Any textbook about quantum field theory should have a proof that Maxwell's equations + Lorentz Force Law are the classical limit of QED. (Although sometimes it's left as a homework exercise.)

@DanielSank - if you make that comment into an answer I'll give you the bounty...

comment Can the energy/power required to mix two fluids together be calculated?
Definitely requires a full numerical model of the shape of the container, shape and speed of the paddle, etc. Just knowing the work is not going to help.
