Chapter 2 & 3: States of Matter and Physical and Chemical Properties
This unit is on chemical and physical properties and how they relate to conservation of matter. Students will learn the the different types of physical properties (boiling point, melting point, density, magnetism, hardness, freezing point, and electric conductivity), chemical properties (reactivity), and the signs of a chemical reaction. They will also learn that mass is neither created or destroyed, but always conserved.
State Standard Covered:
H.2P.2 Explain how physical and chemical changes demonstrate the law of conservation of mass.
What you should be able to do at the end of this unit:
1. I can compare and contrast chemical and physical changes, and give examples of each process.
2. I can write a definition to the law of conservation of mass.
3. I know the names of the four states of matter, and I know their characteristic properties of each state.
4. I can explain the Kinetic Molecular Theory in a solid, liquid and gas
5. I can define mass and volume and calculate the density of objects using the formula D = m/v
Exceeds:
I can explain the Kinetic Molecular Theory and apply it to the behavior of molecules in solids, liquids, and gases.
I can use starting mass of a substance and show, with numbers, what it’s end products will be after a chemical change.
I can use chemical and physical properties of a substance to identify them.

a. freezing point c. reactivity
b. boiling point d. density
11. Ice floats in water because it is
12. Matter that has a definite volume but no definite shape is a
13. If you move a substance from one container to another and its volume changes, the substance is a
14. Which of the following is NOT a clue that a chemical change has occurred?
a. change in color c. formation of a precipitate
b. production of a gas d. change in shape
15. Explain how the kinetic theory relates to a substance state of matter.
Answers:
1. Density. 2. Physical Property. 3. Conservation of Matter/mass 4. Precipitate 5. volume. 6. Kinetic 7. Solid. 8. the molecules move
9. energy. 10. C. 11. less dense than water. 12. Liquid. 13. Gas. 14. D.
15. All atoms are vibrating/in motion in a substance. The faster the molecules move the more likely it is to change state. A substance state of matter is determined by the amount of kinetic energy it has, less energy lends itself to a solid, while more energy can form a liquid or gas.
