The density of copper is 8.96 g/cm3, its molar mass is 63.5 g/mol, and it has one conduction electron per atom. (a) calculate the fermi energy. (b) calculate the fermi velocity. (c) use the drude model to estimate the conductivity. (d) calculate the fermi temperature, defined by kbtf = ef. explain why, (e) assuming t = 0, calculate the total energy of the electron gas for a mole of copper. (f) notice that, in general, the total energy of an electron gas is dependent on its volume. if one were to try to reduce this volume, the energy of the electron gas would increase. (why? ) this requires work. if the compression is quick, it can be considered adiabatic, i. e. there is no heat exchange with the environment thus, detot dw = -pdv, or p -deto/dv. this is called the degeneracy pressure. calculate the de no matter the environmental conditions, a copper wire can always be considered "cold". (numerically) the bulk modulus of a substance tells us som ething racy pressure of about its compressibility; specifically it is the ratio of a small decrease in pressure to the resulting fractional increase in volume and is defined to be b = -v dp/dv. calculate the bulk modulus of copper
