Title: States of Matter


1
States of Matter
  • Chapter 3 Section 1

2
Solids
  • Solids have a definite shape and volume
  • Particles in a solid are closely packed together.

3
Types of Solids
  • 1. Crystalline Solids
  • Particles form regular, repeating patterns.
  • Melt at specific temperature
  • For example Salt Sugar Ice
  • 2. Amorphous Solids
  • Particles are not arranged in repeated pattern
  • Do not melt at specific temperature
  • For example Rubber, Plastics, Glass

Liquids
  • Liquids have a definite volume, but no specific
    shape.
  • Particles are packed closely, but they are free
    to move around and collide with each other.
  • Fluid Substance that flows.
  • Do liquids have a shape of their own?
  • What shape do liquids take?
  • Why doesnt a liquid have a definite shape?
  • How do the motions of the particles in ice and
    water differ?

Properties of Liquids
  • 1. Surface Tension
  • The molecules of a liquids are attracted to and
    pull towards each other.
  • Can you think of some examples?
  • 2. Viscosity
  • Liquids resistance to flowing depends on size,
    shape and attraction between particles.
  • High Viscosity Slow Flow
  • Low Viscosity Fast Flow
  • Can you think of some examples?

Gases
  • No specific shape OR volume
  • Particles flow freely and either spread out or
    squeeze together depending on the container
  • Constantly moving and colliding in all directions
  • Why dont gases have a specific shape or volume?
  • Draw a diagram of gas molecules in a closed
    container.
  • Then, draw a diagram of what happens if the
    container is opened.
