States Of Matter

Question 1

At what degree does all matters stop moving?

Answer 1

All matters stop moving at -273*

Question 2

Give a definition of solid.

Answer 2

Particles that are close together and can’t move around a lot.

Question 3

Give a definition of liquid.

Answer 3

Particles that are close together and-unlike solids- can move around a little.

Question 4

Give a definition of gas.

Answer 4

Particles that have a lot of energy and can move around freely.

Question 5

What are properties of solids?

Answer 5

• They have a high density due to the particles being close together
• Cannot be compressed due to the particles being extremely close together
• Have a fixed shape because of the close particles
• Cannot diffuse as the particles cannot move

Question 6

What are the properties of liquids?

Answer 6

• Have a fairly high density because of the close particles
• Cannot be compresses because there is very little space between particles
• Takes up the shape of its container because the particles can move
• Can diffuse because the particles are able to change places

Question 7

What are the properties of gases?

Answer 7

• Have a low density because the particles are spaced far apart
• Can be compressed because there is space between particles
• They have fixed shape because the particles move about rapidly in all directions.
• Can diffuse because the particles can move freely
