Liquid

• A matter that has a fixed shape and volume.

• A matter that will take the shape of any container it is placed in and has a fixed volume.

• A matter that can only exist in solid form.

• A matter that has no fixed volume and takes the shape of its container.

Gas

• Matter that has a fixed shape and volume.

• Matter that does not have a fixed shape or volume, but will completely take up all the space in a container.

• Matter that can only exist in solid or liquid form.

• Matter that is always visible and can be touched.

Absorption

• A process where a substance takes in another substance.

• A method of releasing energy.

• A technique for separating mixtures.

Velocity

• The speed of an object regardless of direction.

• How fast an object moves in a certain direction.

• The distance covered by an object in a given time.

Expand

• To decrease in size, number, or amount.

• To remain the same in size, number, or amount.

• To increase in size, number, or amount.

• To transform into a different shape.

Mixing

• Happens when you add two different substances or chemicals together.
