level questions: Particle theory

Question	Answer
What is the definition of particle theory?	That particles in any state of matter stay the same, its the arrangement and their energy that changes
What are the forces of attraction like between particles in a solid object?	Very strong
What is the position and arrangement of particles like in a solid object?	Uniform and close together, with vibration
What do particles do in a solid object, meaning they can't flow like liquids?	Stay in one position
Solid objects are not easily compressed, why is this?	Particles are already very close together
Solid objects are generally very dense, why is this?	Lots of particles in a small volume
What are the forces of attraction like between particles in a liquid?	Not strong, but not weak either
What is the position and arrangement of particles like in a liquid?	Close, but free moving
What it is about particles in a liquid that means they can flow?	They don't keep a definite shape
Liquids are not easily compressed, why is this?	Particles are already very close together
Liquids can be quite dense, why is this?	Quite a lot of particles in small volume
What are the forces of attraction like between particles in a gas?	Very weak
What is the position and arrangement of particles like in a gas?	Far apart and moving in all directions
What it is about particles in a liquid that means they can fill the space they are in?	They move fast and collide with eachother and their surroundings
Gases are easily compressed, why is this?	There is a lot of free space between particles
Gases have a very low density, why is this?	Not many particles in a large volume
