Fluids

• Solids


  • Particles are packed really close together
• Liquids and gases


  • Particles are spread further apart
• Solids


  • Have a definite shape
• Liquids


  • Have a definite volume but not shape
• Gases


  • Have neither a definite shape or volume
• A Can of Hairspray Being Thrown In A Fir

  • The pressure being put in the can expands and pushes against the can
  • The can explodes and the chemicals in the hairspray cause the fire to get bigger
  • The forces of attraction got weaker, so it exploded
  • The motion of the particles go faster
• Why some objects float in water and some objects sink

  • The density of water is 1 g/cm3
  • Objects with density less than 1 g/cm3 will float
  • Objects with density greater than 1 g/cm3 will sink, but can float in the ocean due to the higher density of salt water
• Pascal's Law

  When pressure is put on a confined fluid, equal pressure is created at all points
• Why it was easier to push a smaller syringe

  If the smaller syringe had force put on it and the larger starting was 3x bigger, then the 3x the pressure would be put on the large syringe
