Particle Theory of Matter

Question 1

matter

Answer 1

anything that has weight and takes up space

Question 2

particle

Answer 2

the building blocks that make up matter

Question 3

particle theory of matter

Answer 3

1. All matter is made up of particles
2. Particles are always moving
3. There has to be spaces between particles
4. When you heat up particles they move faster
5. When you cool down particles they move slower
6. Particles are attracted to each other

Question 4

solid

Question 5

solid

Answer 5

overall definition: In this state of matter the particles are held tightly together and well arranged and have a fixed volume and shape and the particles vibrate in their position.

particle arrangement: In this state of
matter particles are held tightly together and well arranged

Volume: fixed

shape: fixed

particle movement: vibrate in their position

Question 6

liquid

Answer 6

overall definition: In this state of matter, particles are close together and have spaces for particles to pass through and particles have random motions. Liquid has a fixed volume but no fixed shape

particle movement: random motions in a restricted space

particle arrangement: close together but not tightly packed and have spaces
for particles to pass through

shape: not fixed
volume: fixed

Question 7

gas

Answer 7

overall definition: In this state of matter, the particles have the most energy and move rapidly in all directions. The particles are widely spaced and randomly placed and have no fixed volume or shape

particle movement: moving rapidly in all directions

particle arrangement: widely spaced, randomly placed

shape: not fixed
volume: not fixed
