Astudy of the properties of electrons electrons of a plasma and high-energy electrons of a solid crystal (able to move in the solid) are examples of fermions. that is, particles that follow fermi-dirac statistics. (for discrete energy levels) exp t or (for a continuum of energy) exprt the quantity e is the fermi energy and g(e) the energy density function. this energy will be assumed constant unless otherwise indicated let us focus on the function f(e)- occupation of an energy level, ε. l. a) study the properties of this function for different temperature values, t, starting at which denotes the probability of exp)1 i. b) derive a linearized expression for f(e) for small r 1.c) discuss on how to fill the energy levels by using a to distinguish electrons in valence conductors

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
