What is the name of the probability distribution that describes the speed of gas particles in a container?

Maxwell-Boltzmann distribution

What factors can affect the shape of the Maxwell-Boltzmann distribution?

temperature and mass of the particles

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

It flattens out and spreads over a wider area

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

It becomes narrower Signup and view all the answers

What happens when gas particles collide with each other?

Some particles gain kinetic energy and speed, while others lose energy and slow down Signup and view all the answers

What is absolute zero and what happens to the motion of particles at this temperature?

Absolute zero is the lowest possible temperature, measured at 0 Kelvin (or about -460 °F). At absolute zero, the motion of particles comes to a near stop because there is so little energy left in the substance. Signup and view all the answers

How is the motion of particles different in solids and gases?

In solids, the motion of particles is more like vibration, while in gases, particles are in a constant state of random motion, flying around in random directions. Signup and view all the answers

What is the Boltzmann distribution used for?

The Boltzmann distribution is used to show the probability of kinetic energy using temperature and can help determine the movement of gas particles. Signup and view all the answers

Why is it difficult to determine the movement of gas particles?

Determining the movement of gas particles is difficult due to their constant state of random motion and the need to account for factors such as temperature and energy. Signup and view all the answers

What is the Maxwell-Boltzmann distribution?

The Maxwell-Boltzmann distribution is a probability distribution of the speed of any given particle of gas in a system. Signup and view all the answers

Why do gas particles constantly fly around?

Gas particles constantly fly around because they prefer to keep their space and collisions between particles occur. Signup and view all the answers

How does temperature affect the Maxwell-Boltzmann distribution curve?

Temperature affects the Maxwell-Boltzmann distribution curve by either flattening and spreading out or becoming narrower and taller. Signup and view all the answers

What does a flatter Maxwell-Boltzmann distribution curve indicate?

A flatter curve indicates that more speed options are possible for a given particle, but the probability of having that speed is lower. Signup and view all the answers

What does a narrower, taller Maxwell-Boltzmann distribution curve indicate?

A narrower, taller curve indicates that fewer speeds are possible, but the ones that are possible are more likely for that particle. Signup and view all the answers

Why is the probability of picking a car greater when there are fewer speed possibilities?

The probability of picking a car is greater when there are fewer speed possibilities because the options are more limited. Signup and view all the answers

How do collisions between gas particles affect their speeds and directions?

Collisions between gas particles change the speed and direction of the particles involved in the collision. Signup and view all the answers

How does the temperature of Earth affect the behavior of gas particles?

The temperature of Earth, being well above absolute zero, causes gas particles to constantly fly around and collide with each other. Signup and view all the answers
