Gas Laws

Question 1

Kinetic molecular theory

Answer 1

• gas particles are in constant random straight line motion
• collisions are elastic (conservation of energy)
• the volume of gas particles is negligible (tiny) compared to he space they occupy
• there are no forces of attraction between gas particles

Question 2

Conditions to behave ideally

Answer 2

-raise temperature
-release pressure
-most ideal: oxygen and helium
-real gases deviate from KMT
(Big and some attractions)

Question 3

Properties of gases

Answer 3

-gases have mass
-gases are compressible
-gases have no definite shape or volume (fill the container)
-gases will diffuse
(The smaller the gas the faster rate of diffusion)
