1 1.0 Fluids are used in Technological devices and common everyday materials Key Concepts Workplace Hazardous Materials Information System (WHMIS) and safety fluid properties What does the acronym W.H.M.I.S. stand for? W H M I S Recognition of WHMIS symbols is important to lab safety. Identify the following WHMIS symbols. Fluids are used in many different ways. Describe how fluids are used in the following processes: Slurries Glass Production Toothpaste
2 Give examples of practical applications for each of the following fluid properties: viscosity density buoyancy hydraulics pneumatics 2.0 The properties of mixtures and fluids can be explained by the particle model of matter. Key Concepts organization of pure substances and mixtures concentration and solubility factors affecting solubility The particle model Matter can be organized in different ways. One way is as solids, liquids, and gases. Another way is as mixtures and solutions. Complete the Organizational Chart Describe a suspension, a colloid, and an emulsion. _
3 Describe the process of paper chromatography and give examples of practical applications. What conditions must be present to enable a material to dissolve in another material? Explain the difference between a solute and a solvent. Describe the difference between Concentration and Solubility. (24-28) What is a saturated solution? (p.21) Why are some substances insoluble? What factors affect solubility? Why is water referred to as the universal solvent? What is an aqueous solution?
4 How does temperature affect solubility? The Particle Model of Matter (p.33) What are the 4 key principles explained using the Particle Model of Matter? Illustrate the action of particles in solids, liquids and gases. Solids Liquids Gases What factors affect the rate of dissolving? 3.0 The properties of gases and liquids can be explained by the Particle Model of matter Key Concepts Viscosity Density Buoyancy Pressure What is viscosity, how is it measured?
5 Describe some practical applications using knowledge about viscosity. How is viscosity affected by temperature? What formula is used to calculate density? How are mass and volume related, when determining density? Describe the density of solids liquids and gases, using the particle model. What is buoyancy and how is it determined? Describe how a ship (made out of steel) can float.
