Summary

Properties of the three states of matter 

In a nutshell 

The three states of matter will behave differently depending on their particle arrangement and the attraction between neighbouring particles.  



States of matter 

There are three states of matter - solids, liquids and gases. All materials will be in one of these forms and they are made from particles.


Examples

solids

liquids

gases

Paper

Water

Air

Wood

Milk

Helium

Plastic

Juice

Oxygen

The type of material it is and its properties influences its arrangement of these particles and how well they stick together. How well particles stick together depends on three things:

1.
Type of material
2.
Temperature
3.
Pressure


Examples
  • When pressure is applied to gases they can become liquid.
  • When heat is applied to solids they may become liquid. This is demonstrated when solid ice becomes liquid water when heated.



Properties

Definition

Properties of a substance refers to how they behave; solids, liquids and gases can be distinguished based on their properties

Solid

Fixed volume

Fixed shape

High

Not easily compressed

Does not flow

Liquid

Fixed volume

No fixed shape - takes the shape of any container

Medium

Not easily compressed

Flows easily

Gas

No fixed volume - fills any shaped container

No fixed shape - becomes the shape of the container

Very low

Easily compressed

Flows easily


Some of the states of matter have similar properties to each other.


Example

Name the only state of matter with a fixed shape. 


Solids are the only state of matter with a fixed shape.
