Flashcards

Properties of Solids

Have a fixed shape and volume, incompressible, high density. Particles tightly packed with strong attraction.

Properties of Liquids

Fixed volume but take shape of container, less compressible, lower density than solids. Particles can move past one another.

Properties of Gases

No fixed shape or volume, highly compressible, low density. Particles are far apart and move freely.

Melting

Transition from solid to liquid at the melting point with heat absorption.

Effects of Temperature on Gas Volume

Increasing temperature leads to increased kinetic energy, causing gas volume to increase; decreasing temperature leads to decreased volume.

Effects of Pressure on Gas Volume

Increasing pressure pushes gas particles together, decreasing volume; decreasing pressure allows particles to spread, increasing volume.

Kinetic Particle Theory

As heat is added, particles gain energy; solids melt and liquids boil. As heat is removed, gases condense and liquids freeze.

Study Notes

States of Matter: Solids, Liquids, and Gases

  • Solids:

    • Shape: Fixed shape
    • Volume: Fixed volume
    • Compressibility: Incompressible
    • Density: High
    • Particle Arrangement: Tightly packed in a regular pattern, vibrating around fixed positions
    • Intermolecular Forces: Strong forces of attraction between particles

  • Liquids:

    • Shape: Takes the shape of its container
    • Volume: Fixed volume
    • Compressibility: Less compressible than gases
    • Density: Lower than solids
    • Particle Arrangement: Closely arranged, but particles can move past one another in a random arrangement
    • Intermolecular Forces: Weaker forces of attraction than solids

  • Gases:

    • Shape: No fixed shape
    • Volume: No fixed volume, fills the container
    • Compressibility: Highly compressible
    • Density: Low
    • Particle Arrangement: Particles are far apart and move rapidly in all directions
    • Intermolecular Forces: Negligible forces of attraction

Changes of State

  • Melting: Solid to liquid; occurs at the melting point with heat absorption
  • Boiling: Liquid to gas; occurs at the boiling point with heat absorption
  • Evaporation: Liquid to gas; occurs at any temperature below boiling point with heat absorption
  • Freezing: Liquid to solid; occurs at the freezing point with heat release
  • Condensation: Gas to liquid; occurs at the boiling point with heat release

Effects of Temperature and Pressure on Gases

  • Temperature:
    • Increase in temperature = increase in kinetic energy of gas particles = increase in volume
    • Decrease in temperature = decrease in kinetic energy of gas particles = decrease in volume
  • Pressure:
    • Increase in pressure = decrease in volume (particles forced closer together)
    • Decrease in pressure = increase in volume (particles can move further apart)

Kinetic Molecular Theory and Gas Behavior

  • Heating: Adding heat increases kinetic energy of particles, causing changes in state from solid to liquid or liquid to gas
  • Cooling: Removing heat decreases kinetic energy of particles, causing changes in state from gas to liquid or liquid to solid.
  • Kinetic Molecular Theory on Gas Behavior:
    • Temperature: Higher temperature leads to faster particle movement and larger volume.
    • Pressure: Increased pressure leads to smaller volume and vice versa.
