Particle Model

Question 1

What properties does solids have?

Answer 1

*have a fixed volume and a fixed shape

*cannot flow, because their particles cannot move from place to place

*cannot be easily compressed, because their particles are close together with no space to move into

Question 2

What properties does liquids have?

Answer 2

*have a fixed volume but no fixed shape

*can flow and take the shape of their
container, because their particles can move around each other

*cannot be easily compressed, because their particles are close together with no space to move into

Question 3

What properties does gases have?

Answer 3

*have no fixed shape or volume

*can flow and completely fill their container, because their particles move quickly in all directions

*can be compressed, because their particles are far apart with space to move into
