The features of the material e.g. is it strong
Can you compress a gas?
Yes - because its particles are far apart
Q

Solid
Liquid
Gas

Q
What is a mixture?
A mixture is something that is made from lots of different types of particles e.g. air is a mixture of different particles.
Does a gas have a fixed shape?
No - they can take the shape of the container that they are in e.g. a balloon
Does a gas flow? (can it be poured?)
A
Yes - because gas particles are free to move around
Does a solid flow? (can it be poured?)
No
What is matter?
