Missing: five | Show results with:five

I get 165 using an equation I derived (which is correct), but when I do it the manual way I'm short by 36... This question is too much to ask of you to do the manual way, particularly on an exam. DISCLAIMER: LONG ANSWER! (obviously) METHOD ONE: DRAWING OUT MACROSTATES I'm going to do this a bit out of order, because having one particle per box is the most confusing one. 1) All particles in the same box Here is the representative macrostate: With 9 boxes, you get bb9 ways to have three-particle boxes. 3) Different boxes in the same row Here is the representative macrostate: With two particles in the same box, you have 6 configurations of the remaining particle in its own box within the same row. With 3 rows, that gives bb18 configurations. 4) Different boxes in the same column Here is the representative macrostate: Rotate the box 90^@, then repeat (3) for bb18 more, except we would have technically done it column-wise because the boxes are distinguishable. 5) Different boxes in different rows AND columns (at the same time) Here is the representative macrostate: You should get 4 configurations with one two-particle box in the upper left, times three columns for the two-particle box within the same row equals 12 configurations. Multiply by the three rows to get bb36 configurations. 2i) Each particle in its own box, row-wise Play around with this. You should get: a) All particles in the same row: 3 configurations Here is the representative macrostate: b) Two particles in the same row: 2 configurations if two particles are in the first two columns, 2 configurations if the particles are in columns 1 and 3, 2 configurations if the particles are in the last two columns, times 3 rows, for 18 total. Here is the representative macrostate: c) All particles in different rows: 2 diagonal configurations, 4 configurations with two particles on the off-diagonal, for a total of 6. Here is the representative macrostate: Apparently, I get 3 + 18 + 6 = bb27 here. 2ii) Each particle in its own box, column-wise Play around with this. You should get: a) All particles in the same column: 3 configurations Here is the representative macrostate: b) Two particles in the same column: 2 configurations if two particles are in the first two rows, 2 configurations if the particles are in rows 1 and 3, 2 configurations if the particles are in the last two rows, multiplied by the 3 columns, for 18 total. Here is the representative macrostate: c) All particles in different columns: We don't count these, because they are redundant. Apparently, I get 3 + 18 = bb21 here. However, that only accounts for 129 microstates. That's not enough. Maybe I missed 36 in (5)? METHOD TWO: DERIVING AN EQUATION We begin with the assumption of N distinguishable particles in g distinguishable boxes. If we arrange the boxes linearly, it doesn't change the number of microstates. They would each be separated by g - 1 box walls, shown as |: "x x" cdots | "x x x" cdots | "x x" cdots The walls are distinguishable, and thus could be swapped to obtain distinctly different configurations. With some amount of distinguishable things, there are a factorial number of ways to arrange them. So, there are (g - 1 + N)! arrangements if the particles and boxes are both distinguishable. However, we wish to keep the box walls fixed and the particles are indistinguishable. To avoid double counting, we then divide by N! and (g-1)! to account for redundant wall configurations and to ignore identical configurations of indistinguishable particles. This gives bb(t = ((g + N - 1)!)/(N!(g-1)!)" microstates") when the N particles are indistinguishable and the g boxes are distinguishable. This matches the equation shown in Statistical Mechanics by Norman Davidson (pg. 66). To check this equation, we put bb3 indistinguishable particles in bb4 distinguishable boxes to get: color(blue)(t) = ((4 + 3 - 1)!)/(3! (4 - 1)!) = (6!)/(6 cdot 6) = (5! cdot cancel6)/(cancel6 cdot 6) = (120)/6 = color(blue)(20) microstates color(blue)(sqrt""), just like the example shows. In your case, with bb3 indistinguishable particles and bb9 distinguishable boxes: color(blue)(t) = ((9 + 3 - 1)!)/(3! (9 - 1)!) = (11!)/(6 cdot 8!) = (cancel(8!) cdot 9 cdot 10 cdot 11)/(6 cdot cancel(8!)) = color(blue)(165) microstates So we were short by 36 in our manual guess...

The three distributions of particles at left each have the same energy, the same kind of particles, and the same number of particles, yet the distribution at the right is 30 times more likely than the one at the left. Why is this? For the distinguishable particles which are presumed by the Maxwell-Boltzmann distribution, it matters not only how many particles are in each state, but which particles are in each state.

## FAQs

### What is the number of macrostates of five particles are distributed in two phase cells? ›

Then number of macrostates is : **6**.

**How many microstates are there for 4 particles? ›**

The number of microstates possible for such a system is **n ^{N}**. For example, distributing four particles among two boxes will result in 2

^{4}= 16 different microstates as illustrated in Figure 18.3.

**What is the number of microstates for the system of four particles to be distributed in two cells? ›**

The total number of microstates for the system of four particles is, therefore, 1+4+6+4+1=16=**2 ^{4}**. In general, total number of microstates for the system of n-particles in 'two compartment' composition is 2n.

**How many microstates are there for distinguishable particles? ›**

For distinguishable particles, there are **N2** microstates. This is because are N choices for where to place particle 1, and N choices for where to place particle 2. Meanwhile, the probability p that two particles will be in the same box is 1/N.

**What is the number of microstates in each macrostate? ›**

The number of microstates corresponding to a macrostate is called the **density of states**. It is written Ω(E,V,…), where the arguments are the macroscopic variables defining the macrostate.

**How many microstates are possible for a system of 6 particles? ›**

4. A system of N particles will have 2N microstates, since each of the particles can be in one of the two states (on the left or on the right), and its probability to be in one of them is independent of positions of the other particles. Therefore, there are 2^{6} = **64** possible microstates for six particles.

**What are the 6 microstates? ›**

The European microstates or European ministates are a set of very small sovereign states in Europe. In modern contexts the term is typically used to refer to the six smallest states in Europe by area: **Andorra, Liechtenstein, Malta, Monaco, San Marino, and Vatican City (the Holy See)**.

**What is the total number of microstates? ›**

It turns out there are six possible ways to accomplish this distribution of energy. The diagram below illustrates each of these distributions that we have mentioned. You can see that there are **10** total possible distributions (microstates).

**Does more particles mean more microstates? ›**

**As you add more particles to the system, the number of possible microstates increases exponentially** (2^{N}). A macroscopic (laboratory-sized) system would typically consist of moles of particles (N ~ 10^{23}), and the corresponding number of microstates would be staggeringly huge.

**What can be the number of particles in a phase cell or energy state according to FD statistics? ›**

In summary, according to the Fermi-Dirac statistic, the number of particles in a phase cell is **limited to 1** due to the Pauli exclusion principle. This principle ensures that no two identical fermions can occupy the same quantum state simultaneously.

### How is the number of microstates in a system W related to the entropy of the system S? ›

**The probability that a system will exist with its components in a given distribution is proportional to the number of microstates within the distribution**. Since entropy increases logarithmically with the number of microstates, the most probable distribution is therefore the one of greatest entropy.

**What is the number of particles distribution? ›**

The number distribution is **the number of particles counted of each size, shown as a differential across total number of counts**. I.e. if there were nine particles spread evenly over three sizes the number differential would be 33.3% for each size.

**What is the phase space of the microstates? ›**

The microstate in phase space

**If the position and momentum of two particles are exchanged, the new state will be represented by a different point in phase space**. In this case a single point will represent a microstate. If a subset of M particles are indistinguishable from each other, then the M!

**What are the microstates of atoms? ›**

Microstates are **the specific energy states and arrangement of molecules or atoms in a system in a given instant**. Microstates are essentially snapshots of the macrostates. A macrostate precisely describes an entire system's pressure, density, volume, temperature, etc.

**What is the probability of a macrostate? ›**

The probability of a macrostate is defined as **the ration of the ratio of the number of microstate (i.e. thermodynamic probability W) in it to the total number of possible microstate of the system**. Ex-if there are only 2 compartments or cell, then the total no. of microstate of the system=2n.

**What are the microstates and macrostates of a system of particles? ›**

In physics, a microstate is defined as the arrangement of each molecule in the system at a single instant. A macrostate is defined by the macroscopic properties of the system, such as temperature, pressure, volume, etc. For each macrostate, there are many microstates which result in the same macrostate.

**Is entropy the number of Macrostates in a system? ›**

Boltzmann's principle

Ludwig Boltzmann defined entropy as a measure of the number of possible microscopic states (microstates) of a system in thermodynamic equilibrium, consistent with its macroscopic thermodynamic properties, which constitute the macrostate of the system.

**What is the probability of a microstate and a macrostate? ›**

**A macrostate is characterized by a probability distribution of possible states across a certain statistical ensemble of all microstates**. This distribution describes the probability of finding the system in a certain microstate.
