1cohesionone factor that makes liquids more viscous is called cohesion
2cohesion cont.Fluids with slower flow rates such as maple syrup have particles with greater cohesion.
Less viscous liquids such as water and milk show less cohesion.
3adhesionAdhesion is the forces of attraction between the fluid and what ever comes in contact with the fluid.
With less viscous fluids – less adhesion = ( milk – small residue)
More viscous – more adhesion = (Corn syrup – lots of residue – lots of clean up).
4what adhesion causes?Adhesion causes gases and liquids to travel faster near the center of pipes and tubes than at the edges.
5fluidsfluids are materials that fixed shape. they fill the shape of whatever is surrounding them, (they are free flowing).
6liquidsliquids are a form of fluids that has volume that can be measured.
7gaseswhen particles have low viscosity and density it turns into gases.
8solidswhen paritcles of an item has a high level of vicosity and density it is a solid.
9the particle theorythe particle theory is a way to explain why fluids act the way they do. it also explains what matter is made of and how it acts.
10viscosityviscosity specifics the thickness of a fluid.
11flow ratehow slow or fast a fluid moves.
12densitydensity is the mas of a given volume. the formula of density is mass/volume.
