I'm struggling with the same problem of distinguishing Fermi level from Fermi energy. So when the temperature is at 0 K, where is the Fermi level in relation to the valence band and conduction band edges? Is the Fermi level between them? Or is the Fermi level at or below the valence band...

Thanks so much, bucher. I forgot the difference between heat capacity and molar heat capacity. Thanks again! :smile:

Sorry, I'm still confused..:confused: How did you arrive to this?

How do I find \gamma, though? \gamma = CP/CV I don't know either values of CP or CV.. BTW, I recently found the answer in the back of the book. The new radius is supposed to be 1.09 mm, but I still don't get how they got to this..

An explosive liquid at temperature 300 K contains a spherical bubble of radius 5 mm, full of its vapour. When a mechanical shock to the liquid causes adiabatic compression of the bubble, what radius of the bubble is required for combustion of the vapour, given that the vapour ignites...
