12 - Chapter 42 Challenge Problem 42.53 part A Consider a system of N free electrons within a volume V. Even at absolute zero, such a system exerts a pressure p on its surroundings due to the motion of the electrons. To calculate this pressure, imagine that the volume increases by a small amount dV. The electrons will do an amount of work pdV on their surroundings, which means that the total energy Etot of the electrons will change by an amount dEtot = pdV. Hence p = dEtot/dV. The pressure of the electrons at absolute zero is 32/3+/3h2 N 5/3 Request_Ansc (O ? Help O) Review I Constants Evaluate this pressure for copper, which has a free-electron concentration of 8.45 x 1028 m 4 Express your answer in pascals. Submit
