Chapter 12: Q22P (page 508)

Consider an object containing 6 one-dimensional oscillators (this object could represent a model of 2 atoms in an Einstein solid). There are 4 quanta of vibrational energy in the object. (a) How many microstates are there, all with the same energy? (b) If you examined a collection of 48,000 objects of this kind, each containing 4 quanta of energy, about how many of these objects would you expect to find in the microstate 000004?

Short Answer

Expert verified

number of microstates = 126

number of objects = 380.95

Step by step solution

01

Given data

Number ofID oscillators (N) = 6

Quanta (n) = 4

02

(a) Determine the number of microstates

The no. of microstates,

惟=(n+N-1)!n!(N-1)!鈥�鈥�鈥�=(4+6-1)!4!(6-1)!鈥�鈥�鈥�=126

03

(b)Determine the number of objects

The no. of objects is given by,

n1=collectionofobjects惟鈥�=48,000126鈥�=380.95

How many different ways are there to arrange 4 quanta among 3 atoms in a solid?

Buckminsterfullerene, C60, is a large molecule consisting of 60 carbon atoms connected to form a hollow sphere. The diameter of a C60 molecule is about 7脳10-10 m. It has been hypothesized that C60 molecules might be found in clouds of interstellar dust, which often contain interesting chemical compounds. The temperature of an interstellar dust cloud may be very low; around 3 K. Suppose you are planning to try to detect the presence of C60 in such a cold dust cloud by detecting photons emitted when molecules undergo transitions from one rotational energy state to another. Approximately, what is the highest-numbered rotational level from which you would expect to observe emissions? Rotational levels are l= 0, 1, 2, 3, 鈥�

Young鈥檚 modulus for copper is measured by stretching a copper wire to be about 1.2脳1011N/m2. The density of copper is about 9g/cm3, and the mass of a mole is .Starting from a very low temperature, use these data to estimate roughly the temperature T at which we expect the specific heat for copper to approach 3 kB . Compare your estimate with the data shown on a graph in this chapter.

At sufficiently high temperatures, the thermal speeds of gas molecules may be high enough that collisions may ionize a molecule (that is, remove an outer electron). An ionized gas in which each molecule has lost an electron is called a 鈥減lasma.鈥� Determine approximately the temperature at which air becomes a plasma.

A nanoparticle containing 6 atoms can be modeled approximately as an Einstein solid of 18 independent oscillators. The evenly spaced energy levels of each oscillator are4脳10鈭�21鈥凧apart.
