Question 1

How can you increase pressure

Answer 1

By increasing temperature or reducing the volume

Question 2

What happens when temperature increases

Answer 2

When you increase temperature it makes the particles move faster and volume stays the same
It has two effects:
- Hit the wall harder
- They hit more often
Both increase pressure

Question 3

What happens when you reduce the volume?

Answer 3

Reducing the volume increases pressure
because particles are squashed up into a smaller space so they’ll hit the wall more often

Question 4

How do particles spread out?

Answer 4

By diffusion

Question 5

How does a smell diffuse through a room

Answer 5

The smell of particles from an area of high concentration to an area of low concentration

Question 6

Why does the smell diffuses slowly

Answer 6

The smell diffuses slowly because of particles bumping into air particles which stops them from making a forward progress and often sends them in a completely different direction
