Physical Science Chapter 2 Study Guide
Any substance that has mass and takes up space.
Matter that is pure and has a specific composition and specific properties.
A property of a pure substance that you can observe while keeping it as the same substance.
A property of pure substances that shows its ability to change into other pure substances.
A substance that is pure and cannot be broken down further by chemical or physical ways.
The building blocks of elements. They are the basic particles that make up elements.
The attraction force that binds two atoms together.
Chemically bonded atoms in groups of 2 or more.
Pure substance that is made up of 2 or more elements in a specific ratio chemically bonded.
Chemical formulas show the ratio of atoms along with the elements in the compound.
Chemically not bonded substances that reside in the same place but do not chemically combine.
A mixture where you can visually see the different parts of the mixture.
A mixture that the substances mixed together are not visible.
Another word for Homogeneous mixture.
A change in matter where only the substance’s physical appearance or form without changing the substance’s chemical properties.
A change in matter where the substance is changed into one or more different substances and the chemical composition is changed.
Law of Conservation of Matter
The Law of Conservation of Matter states that matter can not be created or destroyed using chemical or physical means, only transformed.
the ability to cause change or to do work.
The measure of average energy that random motion of matter particles create.
Total energy of every particle in any object.
A change where energy is absorbed, or taken in.
A change where energy is released.
A form of energy that is stored in the chemical bonds between atoms.
Energy that can travel through space in waves.
Energy that is created from electrically charged particles transferring and moving from one place to another.
Two conductive metal strips where electricity enters or leaves the object.
