  • Solids, Liquids and Gases
    • Density in regular Objects
      • Volume is calculated using Depth x Width x Height
      • Density= Mass/Volume
      • Units are either kg/m3 or  g/cm3
    • Density for irregular Objects
      • Calculating volume for density: Measure out two cylinders and drop the object in one and the difference is the volume.
      • Equation is the same for density of a regular object.
    • Pressure in Solids
      • Pressure= Force (Newtons) divided by Area ( in square meters
      • P= F/A
    • Pressure in Gases
      • Three Ways to increase pressure in Gas:
        • Heat It- There particles have more energy so it hits the wall with a bigger force.
        • Squash it: The particles are being squashed togteher
        • Adding more Gas
      • Due to the particles hitting the wall it exerts a force over and area which is pressure,
    • Pressure in Fluids
    • Boyles's Law
      • Equation: Pressure 1 x Volume 1 = pressure 2 x Volume 2
    • The Pressure Law
      • Pressure 1 / Temp 1 = Pressure 1/ temp 1
      • Always convert temperature to Kelvin adding 273
      • Summarize: With a fixed mass of gas at a constant volume, pressure is proportional to temperature (in Kelvins).
    • States of Matter
      • Solids: Particles are closely packed, Regular structure and Vibrate about fixed positions
      • Liquids: Particles are closely packed, Irregular structure and Random motion within structure.
      • Gases:No fixed position, Move at rapid random motion and are very spread out
