Question 1

What are the three main states of matter?

Answer 1

Solids, liquids and gasses

Question 2

What are the four properties of each state that help define them?

Answer 2

Compression, shape, movement of particles and forces between them.

Question 3

Describe the properties of a solid using the four descriptors (compression, shape, movement, forces between particles)

Answer 3

Compression-no
Shape-fixed shape
Movement-none
Forces between particles-strong

Question 4

Describe the properties of a liquid using the four descriptors (compression, shape, movement, forces between particles)

Answer 4

Compression-small amount
Shape-takes shape of container
Movement-yes
Forces between particles-weaker than solids

Question 5

Describe the properties of a gas using the four descriptors

Answer 5

Compression-yes
Shape-no fixed shape
Movement-yes
Forces between particles-Very very very weak

Question 6

Solid to liquid
Liquid to gas
Vice-versa

Question 7

Answer 7

Melting and freezing

Question 8

What is the process called of a liquid going to a gas and vice-versa

Answer 8

Evapouration and condensation

Question 9

What is the process called of a solid going to a gas and vice-versa

Answer 9

Sublimation and deposition

Question 10

Define pressure

Answer 10

The amount of force that is applied to a surface per unit area. The larger the surface area the lower the pressure
