States of Matter and Changes of State in Solids, Liquids, and Gases

This chapter explores the behavior and properties of solids, liquids, and gases. It covers topics such as the state of matter, changes of state, and the behavior of gases. Learn about the characteristics and properties of each state of matter and how they can undergo phase changes. Understand concepts such as melting, freezing, vaporization, condensation, and the behavior of gases under different conditions.

Presentation Transcript

  1. Unit 1: Chemical Building BlocksChapter 3:Solids, Liquids, & Gases Big Idea: In solids, the particles vibrate in closely packed, fixed positions. In liquids, the particles are loosely connected & collide with one another. In gases, the particles are free to move independently.

  2. 3 Sections • State of Matter • Changes of State • The Behavior of Gases Mrs. Lee - Ch 3

  3. Sec 1: State of Matter KEY CONCEPTS • The particles that make up a solid are closely locked in position & can only vibrate • Compared to particles in a solid, the particles in a liquid are more loosely connected & can collide with & move past one another • In gases, the atoms & molecules are free to move independently Mrs. Lee - Ch 3

  4. Solid Crystalline sold Amorphous solid Liquid Fluid Surface tension Viscosity Gas Sec 1: Key Terms Mrs. Lee - Ch 3

  5. Sec 2: Changes of State KEY CONCEPTS • When a substance melts, the particles in the solid vibrate so fast that they break free from their fixed positions. • When a substance freezes, the particles in a liquid move so slowly that they begin to take on fixed positions Mrs. Lee - Ch 3

  6. Sec 2: Changes of State (cont’d) • Vaporization takes place when the particles in a liquid gain enough energy to move independently, forming a gas • During condensation, the particles in a gas lose enough thermal energy to form a liquid Mrs. Lee - Ch 3

  7. Melting Melting point Freezing Vaporization Evaporation Boiling Boiling point Condensation Sublimation Sec 2: Key Terms Mrs. Lee - Ch 3

  8. Sec 3: The Behavior of Gases KEY CONCEPTS • When working with a gas, it is helpful to know its volume, temperature & pressure • When the temperature of a gas is increased at constant pressure, its volume increases. When the temperature of a gas is decreased at constant pressure, its volume decreases Mrs. Lee - Ch 3

  9. Sec 3: The Behavior of Gases (cont’d) • When the pressure of a gas at constant temperature is increased, the volume of the gas decreases. When the pressure is decreased, the volume increases • When the temperature of a gas at constant volume is increased, the pressure of the gas increases. When the temperature is decreased, the pressure of the gas decreases Mrs. Lee - Ch 3

  10. Pressure Directly proportional Inversely proportional Sec 3: Key Terms Mrs. Lee - Ch 3

  11. Sec 3: Charles’s Law Mrs. Lee - Ch 3
