14 Gases

Question 1

When do gasses occur

Answer 1

When molecules/atoms gain kinetic energy to overcome all intermolecular forces.

Question 2

What happens to gases when enclosed in a container

Answer 2

Gasses will diffuse to fill up the entire volume of a container. Gases will also create pressure when colliding with the container walls but won’t lose energy when doing so (elastic).

Question 3

What forces effect gasses

Answer 3

None, they have too much energy to form attractive or repulsive forces

Question 4

Kinetic energy and kelvin temperature relationship in gases

Answer 4

Kinetic energy is directly proportional to the Kelvin temperature of the Sample.

Question 5

What are ideal gases

Answer 5

Hypothetical Gases with:
- no intermolecular forces
- molecules don’t occupy any volume
- collisions are perfectly elastic (no energy lost when colliding)

Question 6

Real gases

Answer 6

non-hypothetical where molecules occupy space and interact.
