Solids
fixed volume and shape
high-density
The atoms vibrate in position but can’t change location.
The particles are packed very closely together in a fixed and regular pattern.

Slide 9 - Diapositive
Liquids
fixed volume but adopt the shape of the container
less dense than solids (an exception is water) but much denser than gases
The particles move and slide past each other which is why liquids adopt the shape of the container and also why they can flow freely
04 September 2023, Monday
Slide 10 - Diapositive
Gases
NO fixed volume = take up the shape of the container
very low density
Since there is a lot of space between the particles, gases can be compressed into a much smaller volume.
The particles are far apart and move randomly and quickly (around 500 m/s) in all directions
They collide with each other and with the sides of the container (this is how
pressure
is created inside a can of gas).

Be creative.
Present your output.
