Understanding Matter and Energy, Fluids

3.2 describe the relationship between mass, volume, and density as a property of matter. ▹
3.3 explain the difference between solids, liquids, and gases in terms of density, using the particle theory of matter. ▹
3.4 explain the difference between liquids and gases in terms of their compressibility and how their compressibility affects their usage. ▹
3.5 determine the buoyancy of an object, given its density, in a variety of fluids. ▹
3.6 explain in qualitative terms the relationship between pressure, volume, and temperature when a liquid or a gas is compressed or heated. ▹
3.7 explain how forces are transferred in all directions in fluids (Pascal’s law). ▹
3.8 compare the ways in which fluids are used and controlled in living things to the ways in which they are used and controlled in manufactured devices. ▹
