C2 : States of matter Flashcards
What is the kinetic particle theory
The theory that explains the properties of the different states of matter
What is the arrangement and movement of particles in a Solid
Close together
Regular pattern
Vibrate on the spot
What is the arrangement and movement of particles in a Liquid
Close together
Random arrangement
Move around each other
What is the arrangement and movement of particles in a GAs
Far apart
Random arrangement
Move quickly in all directions
Why do solids have a fixed shape and cannot flow
The particles cannot change position
Why can’t solids be compresses or squashed
The particles are close together and have no space
Why do liquids flow and take the shape of their container
The particles can move around each other
Why cant liquids be compressed or squashed
The particles are close together and have no space to move into
Why do gases flow and completely fill their container
The particles can move quickly in all directions
Why can gases be compressed / squashed
The particles are far apart and have space to move into
How can particles in real life be different to the particle theory
Particles can have different mass or size
The force of attraction to other particles
Energy
