OH NO!!!!!!!!!!!!!!! its the FLUIDS QUIZ!!!!!!!!!!!!!!!!!!

[blank_start]Viscosity[blank_end] is the term for measuring how fast a fluid will [blank_start]flow[blank_end]; thickness or [blank_start]thinness[blank_end] of a fluid. A [blank_start]viscometer[blank_end] is an instrument that [blank_start]measures[blank_end] viscosity.

We use these to describe viscosity.

why does viscosity play a role in the chocolate bar factories?

we calculate the volume of irregular solids by measuring the dimensions and then using the formula lwh=V

how do we measure the volume of liquids?

we calculate [blank_start]density[blank_end] by using the formula M/V= D. if a substance floats on another it is [blank_start]less dense[blank_end]. if a substance sinks in another it is [blank_start]more dense[blank_end].

Buoyancy is the tendency to rise or float in a fluid

fishes control their buoyancy using sea bladders

scuba divers control their buoyancy by filling air into their vests

when you control ballast, you use wigs to alter buoyancy

compressibility is the ability to be pressed down into a larger volume
