## What does the Boltzmann distribution show?

The Boltzmann distribution (AKA kinetic energy distribution) is a distribution that describes the amount of kinetic energy that a proportion of gas particles have in a given sample.

**What is Maxwell-Boltzmann theory?**

The Maxwell-Boltzmann equation, which forms the basis of the kinetic theory of gases, defines the distribution of speeds for a gas at a certain temperature. From this distribution function, the most probable speed, the average speed, and the root-mean-square speed can be derived.

### What does the Maxwell speed distribution curve tell us does Maxwell’s theory work for a sample of 200 molecules explain?

Maxwell theory works for large number of molecules so that the statistical distribution is reliable. A sample of 200 molecules is not sufficient to obtain a smooth distribution.

**What does the peak of a Maxwell-Boltzmann distribution show?**

The total area under the entire curve is equal to the total number of molecules in the gas. If we heat the gas to a higher temperature, the peak of the graph will shift to the right (since the average molecular speed will increase).

#### What do you understand by Boltzmann statistics?

In statistical mechanics, Maxwell–Boltzmann statistics describes the distribution of classical material particles over various energy states in thermal equilibrium. It is applicable when the temperature is high enough or the particle density is low enough to render quantum effects negligible.

**What is Maxwell-Boltzmann distribution theory?**

The molecules inside the system travel at varying speeds so two persons named James Maxwell and Ludwig Boltzmann came up with a theory to demonstrate how the speeds of the molecule are distributed for an ideal gas which is Maxwell-Boltzmann distribution theory. Consider a system having n particles occupying a volume V, whose total energy is E. .

## What does the Maxwell-Boltzmann graph tell us?

The Maxwell-Boltzmann distribution is often represented with the following graph. The y-axis of the Maxwell-Boltzmann graph can be thought of as giving the number of molecules per unit speed. So, if the graph is higher in a given region, it means that there are more gas molecules moving with those speeds.

**What is the area under the curve in the Maxwell curve?**

Again, the area under the curve corresponds to the percentage of particles with kinetic energy within the corresponding limits. In the article Derivation of the Maxwell-Boltzmann distribution function, the distribution function of the molecular speeds was derived from the barometric formula.

### What is the Maxwell-Boltzmann distribution function for helium?

For this reason this function of the relative frequency density f (v) is also called Maxwell-Boltzmann distribution function: In equation ( 1 ), m denotes the mass of a particle (not the total mass of the gas!). For a helium particle as assumed for the graph above, the mass is m = 6.6465⋅10 -27 kg.
