Kinetic Molecular Theory

Question 1

Avg Kinetic Energy is Proportional to ?

Answer 1

Temperature

Question 2

The collision of one particle with another

Answer 2

Completely Elastic
Particles do not lose energy when colliding

Question 3

Kinetic Energy is dependent on ?

KE = ?

Answer 3

Mass & Velocity

KE = 1/2mv^2

Question 4

Gases in the same container have the same?

Answer 4

Gases in the same container have the same temperature
Thus the gases have the same KE

Question 5

Lighter or Heavier particles faster?

Answer 5

Lighter Molecules are faster

Heavier molecules must be slower because they have greater mass, but equal KE

Question 6

Mean Free Path

Answer 6

The average distance a molecules travels between collisions

Question 7

Diffusion

Answer 7

The process of molecules spreading out in response to a concentration

Lighter molecules diffuse faster, heavier molecules diffuse slower

Question 8

Effusion

Answer 8

The process of gas molecules escaping from a container to a vacuum through a small hole.
