### Particle Velocity Definition

Particle Velocity is defined as the velocity of a particle in medium as it transmitts a wave. It is also known as Maxwell-Boltzmann Equation or Distribution.

### Maxwell-Boltzmann Distribution

As per the Newton's Equation of Motion the particles in a gas move and collide with each other. However, the Order of Avogadro number 10^23 makes it impossible to trace the particle motion. So, we use the temperature to describe the gas particles.

If you were asked on what is the speed of a particle in gas then Maxwell-Boltzmann distribution answers your question pretty well. The Probability of a Particle having Velocity v is given by f(v) = (m/(2╧Ç*k*T))^(3/2) * 4╧Ç*v┬▓ * Exp(-m*v┬▓/(2*k*T))

• Where m is mass of the particle
• T is the Temperature of the Gas
• v is the velocity
• k is the Blotzmann Constant and k = 1.3806 * 10^(ΓêÆ23) J/K

### Average Velocity of a Particle

According to the Maxwell-Boltzmann Equation we can get the formula for Average Velocity of a Particle in gas by the equation = (8*k*T/(╧Ç*m))^(1/2)

• Where K is the Boltzmann Constant
• T is the Temperature
• m is the mass of particles
• is the average or mean speed

If we were to pick a random particle from gas then it has a velocity on an average.

### How to Calculate Particle Velocity?

Go through the simple measures provided below to easily find out particle velocity. They are in the below fashion

• Initially, determine the mass of the particle.
• Next, find out the temperature of the gas.
• Substitute the known input values in the formula of particle velocity i.e. = (8*k*T/(╧Ç*m))^(1/2)
• Solve the equation further and get the particle velocity in gas easily.

### Frequently Asked Questions on Particle Velocity Calculator

1. What is the Particle Velocity Formula?

The Formula for Particle Velocity is v = (8*k*T/(╧Ç*m))^(1/2)

2. What is meant by Particle Velocity?

Particle Velocity is nothing but the velocity of a particle of a medium when it transmits a wave.

3. What does Particle Velocity depend on?

Particle Velocity depends on the time and where the particle is.
