Solid, Liquid, Gas.
1 of 7
How do we make substances change between the states of matter?
By heating or cooling them.
2 of 7
In a solid, what do the particles do?
Vibrate about fixed positions so the solid has a fixed shape.
3 of 7
In a liquid, how do the particles move?
The particles are in contact with each other but can move about at random, so a liquid doesn't have a fixed shape and can flow.
4 of 7
In a gas, how do the particles move?
The particles are usually far apart and move at random much faster, so a gas doesn't have a fixed shape and can flow.
