comment Is NaCl vapour plasma?
@AbanobEbrahim: my guess is that any ionic solid will form neutral molecules when it vaporises. That's because the energy required to dissociate the molecules is comparable to the energy needed to make a plasma, and that requires very high temperatures. But this is just a guess. You would have to search the literature for experimental measurements to be sure.

comment Time dilation on Satellites due to GR
@Kafros: if you really want to include the effect of the Earth's rotation as Floris suggests then answer a new question and I'll be happy to explain. I'm not sure it's worth it though.

comment Time dilation on Satellites due to GR
@Floris: If someone wants to post this as a question I'd be happy to give a detailed answer. It's pretty straightforward as you just integrate the metric for constant $r$ and $\theta$ and $\phi = \omega tr\sin\theta$. But I think the calculation is unnecessary here.
