Section 1

Question Answer
Fluidany substance that flows
flow ratemeasure of speed of flow
all matter is made of particles
all particles are inconstant motion
all particles in one substance is identical (look the same)
___ effect speed of particlestemperature
there are ___ between particlesspaces
particles have forces of_____ between themattraction
Are there still spaces between molecules when mixed? Yes or NoYes
memorize

Section 2

Question Answer
Viscositya fluid's resistance to flow
unit of viscositythick or thin
Flow rate formuladistance divide time = cm/minute
memorize

Section 3

Question Answer
Densitythe amount of mass contained in a given volume
Density FormulaMass / volume ( I ❤ density)
Salt water has more/less density than sugar watermore
density of water1g/cm3
unit of densityg/cm3
if a object's density is more than water, it willsink
if a object's density is less than water, it willflow
Buoyancya force that pushes up on an object in a fluid
memorize

Section 4

Question Answer
Pressure the amount of force applied to an given area
pressure formulaP= f/a (f = force a = area)
Pressure's unitpascal
1 pacal =1 newton per 1m2 of area
memorize
