Gases around us
A gas is state of matter.
?
There are three states of matter.
Solid Liquid Gas
What's the difference between them?
Take four similar lidded jars.
One has a ball of plasticine inside.
One is half full with water.
One is half full with sand.
One is empty.
What can these four jars tell you about the properties of
the three states of matter?
Make a table showing the three states, explain which is which, and add a list of properties for each state.
Try and do this without looking at the answer. Keep your ideas and then look again in two weeks time to see if your ideas have changed.
Answer here.
It would be good to understand a little about atoms,which helps explain
how the three states of matter work.
Try this page on atoms from our own site.
You may notice at the bottom of that page that the world is a little more complicated and there are actually five states of matter. The last one was discovered in 1925. But who knows if there aren't more to be found.
This animation also explains the difference in the movement of atoms for solids, liquids and gases.
