Viscosity and Flow Rate
Anything that flows
fluid
These are the three states of matter.
gas, liquid or solid
The amount of mass in a certain volume.
density
If the density of an object is less than the density of the fluid the object will do this.
rise/float
The circulatory system is an example of a _________ system.
hydraulic
The speed at which a substance flows
flow rate.
Bonus: other than calculating its flow rate, how else do you measure the viscosity of a substance? Hint: it's a device.
Particles are constantly in motion is one of 3 main points of this.
Particle Theory of Matter
The amount of matter in a substance
mass
For a substance to float in water it needs to have a density less than:_____.
1g/mL
A mechanical device that forces fluids through a system
a pump
Oil is ______ than honey.
less viscous
The particles of this state of matter are further apart.
gas
Double Jeopardy!
How do you determine the volume of an irregular shaped object?
Who invented this method?
Measure the amount of water it displaces
Archimedes
True or false: If something floats, it is said to be buoyant.
True
A system that uses a compressed gas to do work
pneumatic system
Doing this to a liquid makes the substance more viscous.
Cooling it/decreasing temperature
When you do this to a liquid, the particles move faster and farther apart until it turns into a gas.
heat it up; increase temperature
Calculate the density of the following: A 2.0 mL sample of a liquid has a mass of 12g.
6.0 g/mL
This common fluid is actually more dense when in liquid form than when in solid form
water
The _______________ of a substance allows it to become more compact when squeezed
compressibility
If a fluid has a high viscosity what is its flow rate?
low/slow flow rate
When the temperature of a substance decreases, this happens to its volume.
decrease of volume; contracts
what is the mass of a substance that has a density of 5 g/cm3 and a volume of 2 cm3?
10g/cm3
This formula determines the density of an object.
Mass divided by volume
D=M/V
