States Of Matter

Question 1

What’s the kinetic particle theory of matter?

Answer 1

The model that the describes the movement, arrangement and energy of particles in a substance- to explain the physical properties of solids, liquids and gases

Question 2

Give the properties of solids

Answer 2

-fixed volume and shape
-cant flow-particles can’t move from place to place
-cant be compressed-particles are too close together

Question 3

Give the properties of a liquid

Answer 3

-fixed volume but no fixed shape
-can flow and take shape of their container-particles can move around each other
-cant be easily compressed-particles are close together- have no space to move into

Question 4

Give the properties of gas

Answer 4

-no fixed shape or volume
-can flow and completely fill their container-particles can move quickly in all directions
-can be compressed- their particles are far apart and have space to move into

Question 5

Give the name for a substance turning from a solid to gas or gas to solid

Answer 5

Sublimation

Question 6

Why are changes of state physical-not chemical?

Answer 6

No new substances are formed during changes of state
