1 THIS IS FROM LESSON 5 in Student Worktext Activating Strategy- “Engage Your Brain” page 65 Complete #1-2 individually at your seat. Active Reading on Page 65 How is the word definite used in the sentence? Answer: constant, How is the word occupy used? Answer: to take up 1

2 2 Lesson Vocabulary Solid Liquid Gas

3 3 Kinetic Theory of Matter: How much particles move and how often they bump into each other determine the state of matter of the substance. A Solid 1) has a definite volume and shape. 2) Its particles are packed together to form a regular pattern. 3) For most substances, the particles in a solid are closer together than in a liquid.

4 4 #5) Describe: How are particles in a solid like people sitting in a movie theatre? People in a movie theatre are sitting in their seats moving only slightly. Particles in a solid are closely locked in position and can only vibrate in place

5 DO Now With your table group, discuss the characteristics of a solid. I will be asking you to tell me something your group talked about. 5

6 6 Liquid – a substance that has a definite volume but not a definite shape. A liquid has 1) more kinetic energy than particles in a solid do. 2) The Particles are close together but not as close as they are in a solid. 3) Particles in a liquid are not fixed in place and can move from one place to another.

7 7 #6 Describe- How are particles in a liquid like people in a movie theatre lobby? People in the lobby can move around freely. Their motion is limited by the people around them. Particles in a liquid can slide past each other.

8 8 Gases- they do not have a definite volume or shape. 1)A substance in a gaseous state has particles with the most kinetic energy of the three states of matter. 2)There is much more space between gas particles that there is for solids and gases. 3)The space between gas particles can increase with changes in temperature.

9 9 #7 Page 67 Describe – How are particles in a gas like people outside of a movie theatre? 1)People outside are spread far apart and can move feely. 2)Particles in a gas can move freely. 3)The particles have more space between them.

10 10 Solids have a definite shape and volume. #8 Identify word or phrases that describe the properties of solids, liquids, and gases. 1)The castle, like all solid substances, has a definite shape and volume. 2)The particles in a solid are in fixed positions and are close together. 3)A solid can not easily change shape or volume.

11 11 Liquids have a definite volume but can change shape. 1)Like water, all liquids have a definite volume but no definite shape. 2)The particles in a liquid are close together but they are not tightly attached to each other. 3)Particles in liquids can slide past one another and as a result, liquids can flow.

12 12 Gases can change shape and volume. 1)Gases do not have a definite volume or shape. 2)The particles in a gas are very far apart. 3)The amount of space between the particles in a gas can change more easily.

13 13 Visualize It!!!! With your table group, answer #10 on page 69

14 14 Something to THINK ABOUT !!! How would the different states of matter change if the contents of the fishbowl would be transferred to a much bigger rectangular aquarium? On the half sheet of paper, tell me how all three states of matter would change. 1)Solids 2)Liquids 3)Gases

15 15 1)The solids in the fishbowl would not change at all if they were placed in a larger rectangular aquarium. 2)The liquid (water) would take the shape of the new container and would not fill the container. 3)The gas (air bubbles) might spread out more.

16 16 THE MOTION OF THE PARTICLES CHANGES page 70 1)The process by which a solid becomes of liquid is know as melting. 2)As the temperature of a liquid is lowered its particles lose energy and become as solid. This is known as freezing. 3)When substances lose or gain energy, one of two things can happen to the substance: its temperature can change or its state can change.

17 Visual Summary- Pages 72 15) False- solids are made of particles that are locked in place so their volume will not change. 16) True- the particles in liquids are further apart than solids so they can move more freely and flow. 17) True- as the particles spread out the volume of gas increases. 17

18 Lesson 1 Part 2 Review- Page 73 1) Solid -Answer A 2) Liquid- Answer C 3) Gas- Answer B 4) The kinetic theory of matter states that the motion of particles in a substance determines its state of matter. 5)The temperature remains the same because once it starts to change it maintains the same temperature until the change has been completed. Ex. Boiling water will be 100 degrees until all the liquid has become a gas. 18

19 Lesson Review continued- Page 73 6) You could put a gas in a larger container to increase its volume. 7) No, the gas particles in the tank always move freely and fill the volume of the tank. 8) The gas particles would escape into the atmosphere. 9) In reality, real helium atoms are much smaller. 10) The vibration of all the particles is too small to detect with the naked eye. 19
