Particle Motion in Gases

Question 1

What is the pressure of a gas like?

Answer 1

• Pressure of the gas is due to:

- Particles colliding with the walls of the container the gas is held in.

Question 2

How can we increase the pressure?

Answer 2

• ## Increase the number of collisions per second or the energy of each collision.

Question 3

What is the temperature of the gas related to?

Answer 3

• The temperature of the gas is related to the average kinetic energy of the particles.
• Low Temperatures: High Temperature
• Particles have low Ek, - Higher Ek.
• Fewer collisions per second, - More collisions.
• Lower energy collisions - High energy collision
• Low Pressure. - High pressure.
