29Fill in the Blanks for Viscosity(notes will help):
Viscosity is the property that describes a fluid's [blank_start]thickness[blank_end] or [blank_start]thinness[blank_end]. Thicker liquids are [blank_start]more[blank_end] viscous or have a higher [blank_start]viscosity[blank_end]. [blank_start]Flowrate[blank_end] is used to determine viscosity. This is a measure of the [blank_start]time[blank_end] it takes a liquid to travel a certain [blank_start]distance[blank_end]. Viscosity relates to the [blank_start]Particle[blank_end] [blank_start]Model[blank_end] of [blank_start]Matter[blank_end]. Viscosity is thought of as [blank_start]Resistance[blank_end] to [blank_start]flow[blank_end].
- There is [blank_start]internal[blank_end] [blank_start]friction[blank_end] between [blank_start]particles[blank_end]
- [blank_start]Thicker[blank_end] liquids have more attraction between the [blank_start]particles[blank_end], and therefore, more [blank_start]friction[blank_end]
- [blank_start]Heating[blank_end] a substance causes the particles to spread [blank_start]out[blank_end], creating [blank_start]less[blank_end] internal friction
For [blank_start]gases[blank_end], the opposite is true. As they are [blank_start]heated[blank_end], they become more [blank_start]viscous[blank_end].- Athickness

30Fill in the Blanks(notes do not apply, but I have said this many times):

37[blank_start]Bouyancy[blank_end] is the tendancy for materials to rise or float in a [blank_start]fluid[blank_end]. It is also referred to as "[blank_start]Bouyant[blank_end] [blank_start]Force[blank_end]", which is the [blank_start]upward[blank_end] force on objects submerged in fluids. [blank_start]Floating[blank_end] occurs when an object doesn't fall or sink in a fluid, but remains [blank_start]suspended[blank_end].
- ABouyancy
- Bfluid
- CBouyant
- DForce
- Eupward
- FFloating
- Gsuspended
38Check FOUR things that cause floating:
- AArchimedes Principle

- FThe object is less dense than water
- GThe object has air in it
- HThe object has no air in it
- IThe object is very heavy
39Fill in the Blanks for Archimedes Principle:
The [blank_start]Bouyant[blank_end] Force acting on an object [blank_start]equals[blank_end] the [blank_start]weight[blank_end](force of gravity) of the [blank_start]fluid[blank_end] displaced by the [blank_start]object[blank_end].- ABouyant
- Bweight
- Cfluid
- Dobject

40If the Bouyant Force is the same as the gravitational force, the object will neither sink nor float.
- AVerdadeiro

Refers to applying a [blank_start]force[blank_end] to a given amount of [blank_start]area[blank_end]. Can be calculated by [blank_start]dividing[blank_end] [blank_start]force[blank_end] by [blank_start]area[blank_end].- Aforce

- AVerdadeiro
- BFalso
46Fill in the Blanks for Compression of Gases(notes will help):
[blank_start]Gases[blank_end] are compressible because their [blank_start]particles[blank_end] are spread apart, and can be [blank_start]squeezed[blank_end] together. The particles of [blank_start]solids[blank_end] or [blank_start]liquids[blank_end] are packed as [blank_start]tightly[blank_end] as possible, therefore, solids and liquids are [blank_start]incompressible[blank_end].- AGases
- Bparticles
- Csqueezed
- Dsolids
- Eliquids
- Ftightly
- Gincompressible
47Check THREE things that use HYDRAULICS:
