To Find the Number of Electrons Per Unit Volume with Energy

Question 38

Multiple Choice

To find the number of electrons per unit volume with energy between E and E + dE in a metal we must multiply the number of allowed states per unit volume with energy E by:


A) the probability that a state is unoccupied, To find the number of electrons per unit volume with energy between E and E + dE in a metal we must multiply the number of allowed states per unit volume with energy E by: A) the probability that a state is unoccupied, B) the probability that a state is occupied, C) the probability that a state is unoccupied, D) the probability that a state is occupied, E) dE alone.
B) the probability that a state is occupied, To find the number of electrons per unit volume with energy between E and E + dE in a metal we must multiply the number of allowed states per unit volume with energy E by: A) the probability that a state is unoccupied, B) the probability that a state is occupied, C) the probability that a state is unoccupied, D) the probability that a state is occupied, E) dE alone.
C) the probability that a state is unoccupied, To find the number of electrons per unit volume with energy between E and E + dE in a metal we must multiply the number of allowed states per unit volume with energy E by: A) the probability that a state is unoccupied, B) the probability that a state is occupied, C) the probability that a state is unoccupied, D) the probability that a state is occupied, E) dE alone.
