Vocab
Materials that have no fixed shape and are free to flow, such as liquids and gasses.
What are fluids?
This describes the amount of space occupied by an object.
What is volume?
This system uses gas under pressure.
What is a Pneumatic Fluid System?
This object is what scuba divers fill with air to control how much they float.
What is a buoyancy compensator?
This causes particles to slow down and be more closer together.
What is decreasing temperature?
This is the measure of relative volume of fluids or solids as a response to a pressure change.
What is compressibility?
This will change depending on where it is measured.
What is weight?
This system uses liquids under pressure.
What is a Hydraulic Fluid Systems?
This is what happens when you push water away.
What is displacement?
When this happens to a liquid, the volume decreases a little bit, while with gas the volume decreases a lot.
What happens when pressure is increased?
This refers to the measurement of how easily a fluids particles are able to slide past one another.
What is viscosity?
This refers to the amount of matter in an object or substance.
What is mass?
This component keeps the fluid moving in the wanted direction at the wanted time.
What are the valves?
When filled with oxygen, this will help control the depth of a fish in water.
What is a swim bladder?
This is the reason why gasses are able to absorb more pressure.
What is they have more space between their particles?
This refers to the attraction of particles of one substance and the particles of another substance.
What is adhesion?
The term used for the mass to volume ratio, or the amount of matter in a given volume.
What is density?
This component monitors the pressure within the system.
What is the pressure gauge?
This is when an object neither sinks nor floats.
What is neutral buoyancy?
This causes particles to move faster and further apart.
What is an increase in temperature?
This is the measurement of how strongly particles of a fluid are attracted to each other.
What is cohesion?
Density x Volume (grams)
What is the formula for mass?
This component provides a pathway to carry the fluids (e.g. hoses, tubing or pipes),
What are the conductors?
An item will do this until it displaces as much water as it weighs.
What is float?
This changes when fluids are put under pressure.
What is volume?
