Unit 4 Lesson 1 What Are Solids, Liquids, and Gases? Florida Benchmark SC.5.P.8.1 Compare and contrast the basic properties of solids, liquids, and gases, such as mass, volume, color, texture, and temperature. Copyright © Houghton Mifflin Harcourt Publishing Company 2

Unit 4 Lesson 1 What Are Solids, Liquids, and Gases? What’s the Matter? Matter has mass and volume. It cannot be created or destroyed. Mass is the amount of matter in something. Volume is the amount of space something takes up. Copyright © Houghton Mifflin Harcourt Publishing Company 3

Matter Has Properties Matter has physical properties. Unit 4 Lesson 1 What Are Solids, Liquids, and Gases? Matter Has Properties Matter has physical properties. You can observe a physical property without changing the matter into a new substance. Odor, texture, and color are some physical properties.

More Properties Temperature is also a physical property. Unit 4 Lesson 1 What Are Solids, Liquids, and Gases? More Properties Temperature is also a physical property. Temperature is a measure of the energy of motion of the particles in matter. Mass and volume are also physical properties. Copyright © Houghton Mifflin Harcourt Publishing Company 5

More Properties Density is another physical property of matter. Unit 4 Lesson 1 What Are Solids, Liquids, and Gases? More Properties Density is another physical property of matter. Density is found by dividing the mass of an object by its volume. Copyright © Houghton Mifflin Harcourt Publishing Company 6

States of Matter Liquids Unit 4 Lesson 1 What Are Solids, Liquids, and Gases? States of Matter Liquids A liquid is a substance that has a definite volume but does not have a definite shape. Copyright © Houghton Mifflin Harcourt Publishing Company 7

Unit 4 Lesson 1 What Are Solids, Liquids, and Gases? A gas is a substance that does not have a definite shape or volume. Copyright © Houghton Mifflin Harcourt Publishing Company 8

Solids A solid is a substance with a definite shape and volume. Unit 4 Lesson 1 What Are Solids, Liquids, and Gases? Solids A solid is a substance with a definite shape and volume. Copyright © Houghton Mifflin Harcourt Publishing Company 9

States of Matter Matter is made up of tiny particles. Unit 4 Lesson 1 What Are Solids, Liquids, and Gases? States of Matter Matter is made up of tiny particles. The particles in solids, liquids, and gases have different amounts of energy. The amount of energy affects how fast the particles move and how close together they are.

Unit 4 Lesson 1 What Are Solids, Liquids, and Gases? States of Matter The shape and volume of something depends on its state. Gas particles are far apart. They can move around without affecting one another. Gases take the shape and volume of their container. The gas particles spread out to fill the container.

Unit 4 Lesson 1 What Are Solids, Liquids, and Gases? States of Matter The particles in a liquid cannot move around as much as the particles in a gas. The particles in liquids can slide past one another, so liquids take the shape of their container. The particles in liquids cannot move very far from one another. So, a liquid has the same volume no matter what container it is in. Copyright © Houghton Mifflin Harcourt Publishing Company 12

Unit 4 Lesson 1 What Are Solids, Liquids, and Gases? States of Matter The particles in a solid cannot move very much at all. Because the particles in a solid cannot move, a solid has the same shape and volume no matter what container it is in. Copyright © Houghton Mifflin Harcourt Publishing Company 13

Properties of Solids, Liquids, and Gases Unit 4 Lesson 1 What Are Solids, Liquids, and Gases? Properties of Solids, Liquids, and Gases Liquids and gases can flow. Gases can expand, taking up more space, or compress, taking up less space. Solids have definite textures and shapes. Copyright © Houghton Mifflin Harcourt Publishing Company 14
