Gas
The attractive forces between the particles in a gas are…
Very weak

The attractive forces between the particles in a solid are…
Are very strong
What is the reason that a solid has a fixed shape and cannot flow
The particles cannot move from place to place
What is the reason why solids cannot be compressed (squashed)
The particles are close together and have no space to move into
What is the reason that a liquid can flow and take the shape of the bottom of their container
The particles can move around each other
What is the reason why a liquid cannot be compressed (squashed)
The particles are close together and have no space to move into
What is the reason why gases can flow and completely fill their container
The particles can move quickly in all directions
What is the reason why gases can be compressed (squashed)
The particles are far apart and have space to move into
