1. MATTER

2. Anything that has mass and takes up space Mass= amount of “stuff” in a object Volume= amount of space an object takes up Volume= Length x width x height V=LxWxH 1 cm 3 = 1 mL

3. Density Density is the amount of mass in a given space Density determines how heavy an object feels to you D= mass divided by volume D=m/v g/cm 3

4. Matter has four basic states: solid, liquid, gas, and plasma Some elements and compounds are able to transition through all of these phases Others may not be able to become certain states The basic structure does not change (water is always water) States of Matter

5. solid Structurally ridge, resistant to changes in shape or volume Lowest amount of energy is contained in this state Form crystalline structures Particles cannot move in this state Most elements are found in this state (metals)

6. liquid takes the shape of the container it is in, but always has the same volume Particles are allow to move and flow in this state Liquids will not compress their volume Only 2 element are found in this state (Hg and Br)

7. Gases Gases have no defined shape or volume particles are allowed to move freely Many non metal elements are found naturally in the gaseous state

8. Plasma superheated gas that splits atoms into ions Ions- charged particles Most of the matter in the universe is found in this state (stars) contains the most energy Manmade- laser, plasma tv, neon signs

9. changing state of matter To change states of matter we must add energy This type of energy is known as thermal energy (Heat) each phase requires more energy

10. changing states of matter freezing- liquid to solid (loses heat) melting- solid to liquid (gains heat) evaporating- liquid to gas (gains heat) condensing- gas to liquid (loses heat) sublimation- solid to gas (gains heat) deposition- gas to solid (loses heat)
