3 States of Matter Solids, Liquids, Gases

Matter and Particles Matter is everything that has mass & takes up space Matter includes things we can easily observe Matter also includes things not easily seen Mass is the amount of matter something contains. For example: an elephant has a lot of mass; a leaf doesn’t have much mass but both are matter. Matter is made up of small bits called particles.

Particles are so small they can only be seen with the strongest microscopes.

Particles are arranged to form the states of matter: Solids Liquids Gases

Solids have a specific shape take up a definite amount of space particles are very close together. Particles are very tight and stay close to their neighbor. They move together around one single point.

Liquids take the shape of its container take up a definite amount of space Particles slip and slide around each other.

Gas have no specific shape take up no definite amount of space always fill the container it is in Particles do not stay close together. They move around very fast.
