comment Which form of the first law of thermodynamics should I use?
Its not a bad question at all! I am an engineer and I never realized that chemists used a $\Delta U = \delta Q + \delta W$! I always use a $-\delta W$...

comment What determines bubble locations in boiling water?
More bubbles form at aspersions/surface roughness?

comment How long can you survive 1 million degrees?
What temperature needs the er... "denaturization" of skin protein? Seems like a latent heat/thermodynamics/rate of heat transfer/first law of thermodynamics problem! :P

comment Why isn't perpetual motion possible, even though we are so technologically advanced?
@RobertMastragostino But wouldn't you say that the fundamental nature of energy limits technology? One perpetual motion machine (don't quite remember the "type") has no friction but we know that friction exists. Wouldn't a perpetual motion need to be free of the effects of entropy to be in "perpetual motion"? This is an interesting discussion for a sophomore level class that I teach! :)

comment How to describe heat transfer between two solid materials?
Also look at "contact resistance"!

comment $\nabla({\bf u}^2)=2({\bf u}\cdot \nabla){\bf u} - 2(\nabla \times {\bf u}) \times {\bf u}$
Look at pg 68 of Panasatasiou et al.This is a fluid mechanics book available for free.
