Fluid - Any substance that takes the shape of its container. A fluid can be
poured. Both gases and liquids are fluids.
Three States of Matter - Solid, Liquid and Gas.
The Differences in the Number of Molecules for each state of Matter-Usually the
students were sitting in a group on the floor. We told them that they represented the
molecule distribution of a liquid in the area bounded by them. We told them to visulaize
only Tony and I in the room. We then represented the molecule distribution of a gas.
Lastly we asked the students to sit as close together as possible. At that point they
represented a solid's molecules distribution
Density - Density = (mass / volume)
Viscosity - The resistance of a fluid to flow. For a particular
liquid, the greater the viscosity, the greater the density.
Laminar Flow - Flow of a fluid where the Reynold's number is low. (ie/ the smooth
straight line of smoke initially rising from a lit cigarette.)
Turbulent Flow - Flow of a fluid where the Reynold's number is high. (ie/ the
wild and crazy smoke rising from a lit cigarette usually 5 cm from the end of the
Examples of Non-Newtonain Fluids -Cornstarch and water, Ketchup and Blood just
to name a few.
