Grade 8 Science – Study Guide for Sections 7.1, 7.2, 7.3, & 7.5 Know the definitions for: Adhesion Eddy Flow rate Fluid Gas Laminar flow Liquid Solid Surface tension Streamlined Turbulent flow Viscosity  Be able to list the five main points of the Particle Theory of Matter  Be able to give four examples of different types of manufactured products that are fluids in homes (I won’t give 4 marks for 4 different drinks in your fridge…)  Be able to give three examples of fluids in your body that are essential to life and explain how each is essential  Be able to use the particle theory to explain why a liquid takes the shape of the container it is in but does not expand to completely fill the container as a gas does.  Be able to use the particle theory to explain the effect of temperature on the flow rate of liquids and gases  Be able to list three factors that can increase or decrease the flow rate of any particular liquid in a pipe (thus you can’t say ‘type of fluid’ as a factor)  Understand how the flow rate of a liquid is related to its viscosity  Be able to draw a particle diagram of a solid, a liquid, and a gas. Your drawing must include lines and/or arrows to indicate the relative arrangement of the particles, their relative movement/energy and other solid or dashed lines to indicate the strength of the attraction (bonds) between the particles.  Be able to calculate flow rate given volume and time (formula-substitute-solve) with proper units. There will be a bonus for converting from mL/sec to L/min  Be able to give an example of laminar flow
