FLUIDS

LIQUIDS:

    • Water
    • Ketchup
    • Bleach

GASES:

    • Air
    • Smoke
    • Carbon Dioxide

​

a fluid is a material that has no fixed shape and is free to flow (liquids and gases)

PARTICLE THEORY OF MATTER

  • all matter is made of tiny particles
  • particles have empty spaces between them
  • particles are in constant, random motion
  • particles move faster and farther when energy is added as heat
  • particles are attracted to each other

SOLID

  • the particles in a solid are closely packed together
  • vibrate only slightly
  • stay in the same positions

has a definite shape and a definite volume

MRSTAV

13 of 27

LIQUID

  • the particles in a liquid are still close together but…
  • vibrate more
  • are free to move around each other in all directions

has a definite volume but does not have a definite shape (liquids take the shape of the container that they are in)

MRSTAV

14 of 27

GAS

  • the particles in a gas are very far apart
  • vibrate a lot
  • move very fast in all directions

has neither a definite volume or definite shape (gases take the shape and completely fill whatever container they are in)
