Particle Theory
Anything that has mass and takes up space
The term for a fluid’s resistance to flow.
Viscosity
This is the mathematical relationship between mass and volume.
Density= mass/volume
Fluids always flow from an area of high pressure to an area of______
Low pressure
This type of system uses a gas (usually air) under pressure to transmit force.
Pneumatic
These are the two states of matter that are considered fluids because they can flow.
Liquid and Gas
This happens to the viscosity of a liquid as its temperature increases.
Decreases (flows easier)
If a substance's density is greater than the fluid it is in, the substance will d
Sink
This happens to the pressure in a pool as you swim deeper.
Increases
This type of system uses a liquid under pressure to transmit force.
Hydraulic
This term describes the increase in a substance's volume due to an increase in temperature.
Unlike liquids, when heat is added to this fluid, its viscosity increases due to more particle collisions and friction.
Gas
According to Archimedes’ principle, the upward buoyant force is equal to this.
The weight of the fluid displaced
This state of matter is much more compressible than a liquid because there is more space between its particles.
Gas
These are the units used to measure the density of a liquid.
g/mL
This state of matter can flow because its particles can overcome some attraction and slide past one another.
Liquid
This is the speed at which a fluid flows from one point to another.
Flow rate
The density of a cork that has a mass of 3g and a volume of 16cm3
0.19g/cm3
If you have a water bottle with a hole at the top and a hole at the bottom, the water will flow more aggressively out of this hole.
The bottom hole
To find the volume of a rectangular bar before calculating density, you must multiply these three measurements.
Multiply length x width x height
The state of matter in which a substance is typically the most dense.
Solid
Of these four temperatures—10°C, 35°C, 50°C, and 75°C—this one would have the highest viscosity for a sample of shampoo
10 degrees
To rise in the ocean, a sperm whale changes its oil to this consistency to decrease density.
Liquid
You can increase the pressure in a soft football without adding air by doing this.
This is the volume of a ketchup bottle that has a mass of 170g and a density of 0.5 g/mL.
340 mL
