Solid and liquid
Which state(s) of matter are easy to squash? (compressible)
Gas
Which state(s) of matter flow easily?
Liquid and Gas
How do the particles move in a solid?
They cannot move and are in a fixed position.
How do the particles move in a liquid?
They can move past each other
How do the particles move in a gas?
They move very quickly?
What is diffusion?
The random movement of particles until they are evenly spread.
Why can diffusion not happen in a solid?
The particles of a solid are in a fixed potision and cannot move.
What causes pressure?
Particles bumping in to the walls of the container they are in.
What happens to the pressure inside a balloon when you blow it up? Explain why.
The pressure increases because there are more air particles.
Does diffusion happen faster at colder or warmer temperatures? Explain why.
Warmer temperatures because the particles have more energy.
