What are fluids? What are they made of and how do we use them? What properties of fluids are important to their use?

The Penny Boat Challenge

By the time you finish this unit you should be able to:

  • explain the Workplace Hazardous Materials Information System (WHMIS) symbols for labeling substances; and describe the safety precautions to follow when handling, storing and disposing of substances at home and in the laboratory
  • identify examples of fluids in household materials, technological devices, living things and natural environments
  • identify properties of fluids that are important in their selection and use
  • describe examples in which materials are prepared as fluids in order to facilitate transport, processing or use
  • describe and interpret technologies for moving fluids from one place to another
  • distinguish among pure substances, mixtures and solutions, using common examples
  • investigate the solubility of different materials, and describe their concentration
  • investigate and identify factors that affect solubility and the rate of dissolving a solute in a solvent
  • relate the properties of mixtures and solutions to the particle model of matter
  • describe technologies based on the solubility of materials
  • compare fluids, based on their viscosity and flow rate, and describe the effects of temperature change on liquid flow
  • describe and interpret technologies based on flow rate and viscosity
  • observe the mass and volume of a liquid, and calculate its density using the formula d = m/v
  • compare densities of materials; and explain differences in the density of solids, liquids and gases, using the particle model of matter
  • describe methods of altering the density of a fluid, and identify and interpret related practical applications
  • describe pressure as a force per unit area, and describe applications of pressure in fluids and everyday situations
  • compare the compressibility of liquids and gases
