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 $-\delta W$... |

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

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 |

Why perpetual motion wouldn't be possible if we are so technological 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! :) |

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

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

Molecular Dynamics (MD) Simulation: energy fluctuations in NVE ensemble @Nick I wish this answer was around back when I was doing MD half a decade ago! :P |

Phase transition through Molecular Dynamics Studies @Vishnu The RDF peaks/troughs and their distance from each other tells one about the "orderliness" of the state or in other words if it is a solid liquid or gas. I wish I remembered specifics right now!!!! MD Was a previous life for me. J M Haile and Allen and Tildesley are nice books if you haven't got your hands on them yet. Particularly Haile has a fantastic appendix! |
