No definite shape or volume and will always fill any container
they move constantly with random motion
either expand when heated or pressure increases

very Weak forces of attraction so they are free to move and are spread out.
the particles in gas travel in straight lines

There are strong forces of attraction in which holds them close together in fixed position to form a lattice arrangement

Particles don't move from their position and they keep a definite shape and volume
The particles vibrate in their position
the hotter the particles become, the more they vibrate

There is a weak force of attraction between liquid particles. They are free to mave around and past each other but tend to stick close together

Liquids have a definite volume but don't have definite shape and the particles are constantly moving in a random motion
The hotter the liquid gets, the faster the particles move

Diffusion is the gradual movement of particles from a high concentration to a low concentration

Potassium manganate will diffuse in water. The color will slowly spread out into the liquid
