Science - Matter

Matter is anything that takes up space and has mass

Solids

Liquids

Gases

Have a fixed mass

Have a fixed shape

Have a fixed volume

Cannot be easily compressed

Particles cannot flow

Have a fixed mass

Have no fixed shape

Have a fixed volume

Cannot be easily compressed

Particles can flow

Has a fixed mass

Has no fixed volume

Has no fixed shape

Particles can flow

It can be easily compressed

This is when a solid changes into a liquid

This is the temperature a substance melts at

0⁰C

This is changing a liquid into a gas

This is the temperature at which a liquid changes to a gas

100⁰C

This is changing a gas into a liquid

This is changing a liquid into a solid

0⁰C

This is when a substance is heated and they do not melt but turn straight into a gas

They do not form a liquid

This is when matter changes shape or state but no new substance is formed eg. melting and boiling

It is easy to reverse (change back)

There is no change in mass

This is when a new substance is formed eg. rusting

It is not easy to reverse (change back)

There is no change in mass

The Law of Conservation of Mass states that matter cannot be created or destroyed but can change from one form to another
