Particle Theory
These are the three states of matter.
What are Gases, Liquids and Solids
A fluid is any substance that has no fixed shape and can do this.
What is flow?
This is the amount of mass contained in a given volume.
Density
This is the upward force exerted by a fluid on an object that is in it.
What is buoyant force (or buoyancy)?
This is the term for a fluid's resistance to flow.
What is viscosity?
This is the state of matter where particles are tightly packed and vibrate in a fixed position.
What are solids
Both liquids and gases are classified as this type of substance.
What are fluids?
The formula for calculating density is mass divided by this.
Volume
An object will float if the buoyant force is greater than this other force.
What is the force of gravity (or weight)?
A fluid with a low viscosity, like water, will flow more quickly than a fluid with this type of viscosity.
What is a high viscosity?
If you heat a substance, the speed of its particles generally does this.
What is increase speed.
This property of a fluid refers to its ability to be squeezed into a smaller volume.
What is compressibility?
If object A has a density of $1.5 g/mL and object B has a density of $0.8 g/m, object A has more of this.
This is the specific term used to describe an object that remains suspended in a fluid without sinking or floating.
What is neutrally buoyant (or suspension)?
Honey or molasses is a common example of a fluid that is very high in this property.
What is viscosity?
The key difference in particle arrangement between a liquid and a gas is that a gas has much more of this.
Space
In a closed system, a fluid will exert pressure equally in all of these.
What are directions?
**Random**
Compressed air is the main component to this type of system.
What is pneumatic system.
According to Archimedes' Principle, the buoyant force on an object equals the weight of this.
What is the fluid displaced?
If you increase the temperature of most liquids, their viscosity generally does this.
What is decrease?
What is the idea in the Particle Theory.
Everything is made up of particles that are always moving and have space in between them.
This is a real-world device that uses an incompressible fluid to transfer force, such as in car brakes.
What is a hydraulic system (or hydraulic lift)?
If you increase the temperature of most fluids, their volume increases, and their density does this.
What is decrease.
A submarine uses tanks that fill with water or air to change its overall average density and control this.
What is buoyancy?
_____ is the measure of how powerful the attraction between a fluid's own particles are.
What is cohesion
