Matter |
Anything that has mass or volume. Matter exists ordinarily as a solid, gas, or liquid. |
|
Mass |
A measure of how much matter an object is made of |
|
Weight |
The force of gravity on an object |
|
Volume |
An amount of 3 - dimensional space, often used to describe the space that an object takes up |
|
Atom |
The smallest particle of an element that has the chemical properties of that element. |
|
Molecule |
A group of atoms that are held together by covalent bonds so that they move as a single unit. |
|
Element |
A substance that cannot be broken down into a simpler substance by ordinary chemical changes. An element consists of atoms of only one type. |
|
Compound |
A substance made up of two or more different types of atoms bonded together. |
|
Mixture |
A combination of two or more substances that do not combine chemically but remain the same individual substances. Mixtures can be separated by physical means. |
|
States of Matter |
The different forms in which matter can exist. Three familiar states are solid, liquid, and gas. |
|
Solid |
Matter that has a definite shape and a definite volume. The molecules in a solid are in fixed positions and are close together. |
|
Liquid |
Matter that has a definite volume but does not have a definite shape. The molecules in a liquid are close together but not bound to one another. |
|
Gas |
Matter with no definite volume or shape. The molecules in a gas are very far apart, and the amount of space in between them can change easily |
|
Heterogeneous |
Different properties in different areas of a mixture. Can see the different parts |
|
Homogeneous |
The same properties in the same area of a mixture. You can't see the individual parts. |
|
Displacement |
The technique you use to find the volume of irregular objects. |
