States of Matter - Chemistry Year 10

What is difussion?

• spreading of ions from where there is a lot to where there are less

• spreading out of particles from high to low concentration

• process by which a liquid turns into a vapor when it is heated to its boiling point

• High to very very low

How are particles arranged in solids?

• jiggle around

• assume the shape and volume of its container

• assume the shape of the part of the container which it occupies

• tightly packed, in a regular pattern.

It is easy to move around through a gas because there are no forces between the particles. TRUE OR FALSE

• True

• False
