When the conduction electrons in a metal are treated as an ideal gas of fermions, the mean number of electrons occupying a state with energy e is given by i+ (-2) (3)u (a) define the fermi energy [ marks] (b) sketch n as a function of e for an electron gas: (i) at t 0 k, and to the fermi temperature (ii) at a temperature above 0 k, but small compared label and briefly justify each sketch [5 marks] (c) describe the change in the variation of n with e as the temperature increases, and hence explain why conduction electrons make only a small contribution to the heat capacity of a metal at room temperature

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
