Physical Properties and Changes

Definition of Matter anything that has mass and takes up space 1. Water in a bucket

Key concepts Key Concepts Chemistry is the study of matter. 2. Key Concepts Chemistry is the study of matter. Matter is made up of extremely tiny particles called atoms and molecules. Atoms and molecules make up the three common states of matter on Earth—solids, liquids, and gases. The particles of a liquid are attracted to one another, are in motion, and are able to move past one another. Being a solid, liquid, or gas is a property of a substance.

Matter—Solid, Liquid, Gas 4. On Earth, matter is either found as a solid, liquid, or gas.

Matter—Solid, Liquid, Gas 5. particles (atoms or molecules) that make up the solid, liquid, and gas are moving •Matter (solid, liquid, and gas) is made up of tiny particles called atoms and molecules. •The atoms or molecules that make up matter are always in motion. •These first two ideas make up a very important theory called the Kinetic-molecular theory of matter. Basically the state of a sample of matter depends on TEMPERATURE!

Matter—Solid, Liquid, Gas 6. Atoms or molecules that make up solid, liquid or gas are attracted to one another

Comparing matter 7. solids liquids gases attractions Atoms or molecules are very attracted to one another Atoms or molecules are attracted to one another Atoms or molecules are barely attracted to one another movement Vibrate but do not move past one another Vibrate but are able to move past one another Vibrate and move freely past each other Volume and shape Have a definite volume and definite shape Have a definite volume, but does not have a definite shape Does not have definite volume or definite shape 7.

Properties of Matter 9. Matter has both physical and chemical properties. It can also be classified according to these physical and chemical properties.
