Question 29

Question
Fill 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].

Question 37

Question
[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].
Answer

  • fluid
  • Bouyant
  • Force
  • upward
  • Floating
  • suspended

Question 38

Question

  • The average density is less than water
  • The average density is more than water
  • The object is less dense than water
  • The object has air in it

Answer
  • Bouyant
  • weight
  • fluid
  • object

Fill 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].

  • solids
  • liquids
  • tightly
  • incompressible
