Shape & Dimensions of Containers: Impact on the Maxwell Boltzmann Distribution

In summary, the Maxwell Boltzmann distribution does not change depending on the shape of the container when pressure and volume are constant. However, the distribution can be affected by the shape of the container if the gas is in a sphere, cube, or cuboid. The Maxwell Boltzmann distribution also does not look the same in 2 dimensions due to differences in the density of states. The available states do not depend on the shape of the container for a macroscopic system, while the MB-distribution is not applicable for microscopic systems.

TL;DR Summary
I have some basic questions about the Maxwell Boltzmann distribution
1.Does the Maxwell Boltzmann distribution change depending on the shape of the container? Pressure and the volume is constant. How is the Distribution affected whether the gas is in: a,sphere b,cube c,cuboid?
Why does/doesn’t the distribution change depending on the shape of the container? 2.Does the Maxwell Boltzmann distribution look the same in 2 dimensions?

No to both, I would say.

For 2.: The density of states is not the same in 2D so the Normalization factor has to be different.

For 1.: I would think that the available states don't depend on the shape of the container if the container is macroscopic. For a microscopic system the MB-distribution can't be used anyway.

FAQ: Shape & Dimensions of Containers: Impact on the Maxwell Boltzmann Distribution

What is the Maxwell Boltzmann distribution?

The Maxwell Boltzmann distribution is a statistical distribution that describes the distribution of speeds of particles in a gas at a given temperature. It is based on the principles of kinetic theory and is used to understand the behavior of gases.

How does the shape of a container affect the Maxwell Boltzmann distribution?

The shape of a container can affect the Maxwell Boltzmann distribution by changing the available space for the gas particles to move around. This can impact the average speed and distribution of speeds of the particles, thus altering the shape of the distribution curve.

What is the relationship between container dimensions and the Maxwell Boltzmann distribution?

The dimensions of a container, such as its volume and surface area, can affect the Maxwell Boltzmann distribution by influencing the number of gas particles and the rate of collisions between particles and the container walls. This can ultimately impact the shape and spread of the distribution curve.

How does the temperature of a gas affect the Maxwell Boltzmann distribution?

The temperature of a gas is directly related to the average kinetic energy of its particles, which in turn affects the distribution of speeds described by the Maxwell Boltzmann distribution. As temperature increases, the average speed of particles also increases, resulting in a broader and flatter distribution curve.

What other factors can influence the Maxwell Boltzmann distribution?

In addition to container shape and dimensions, and temperature, other factors that can influence the Maxwell Boltzmann distribution include the type of gas, the number of gas particles, and the presence of external forces such as gravity or electric fields. These factors can all impact the average speed and distribution of speeds of gas particles, resulting in different shapes and characteristics of the distribution curve.
