Understanding States of Matter: Solid, Liquid, and Gas with Boyle's and Charles' Laws

This chapter explores the three primary states of matter: solid, liquid, and gas. Solids have a definite shape and volume, like ice. Liquids possess a fixed volume but no fixed shape, such as water, milk, and blood. Gases lack both a definite shape and volume and can expand indefinitely. The differences between liquids and gases are also discussed, along with two important gas laws: Boyle's Law, which states that the volume of a gas decreases as pressure increases at constant temperature, and Charles' Law, which indicates that gas volume increases with temperature at constant pressure.

Presentation Transcript

  1. Chapter 7

  2. Define: solid • definite shape and volume; firm; neither liquid nor gaseous • "ice is water in the solid state"

  3. Define: liquid • readiness to flow, having no fixed shape but a fixed volume • "water and milk and blood are liquid substances”

  4. Define: gas • a fluid having neither independent shape nor volume and being able to expand indefinitely

  5. Ways a liquid is different from a gas. • Has a definite volume • Higher density • Particles are closer together • More attraction between molecules • Does not expand to fill its container

  6. Boyles Law: a fixed amount of gas at a constant temp. volume increases as pressure decreases

  7. Write these three letters on one side of your index card. • Think how you can use this to represent Boyle’s law…. Formula P¹ V¹ = P² V² P T V

  8. Charles Law : a fixed amount of gas at a constant pressure volume increases as temperature increases

  9. Write these three letters on the other side of your index card. • Think how you can use this to represent Charles law…. Formula V¹ = V² T¹ T² T P V
