Density & Pressure

Cards (12)

  • Density is the mass of a given volume of a substance
  • Density in kg/m3, Mass in kg, Volume in m3
  • Density depends on the state of a substance
  • In solids the particles are packed close together
  • In liquids the particles are close together and move around each other
  • In gasses the particles are far apart and move quickly in all directions
  • Solids are usually denser than liquids
  • Liquids are usually denser than gasses
  • Pressure is the force per unit area
  • Pressure in N/m2, Force in N, Area in m
  • Density = Mass/Volume
  • Pressure = Force/Area
