L I Q U I D S

As area increases, pressure ...

• Increases

• Decreases

• Stays the same

• Disappears

Answer explanation

Pressure is inversely proportional to area.

-Small area, Large Pressure

-Large Area, Small Pressure

Liquid pressure depends on what?

• Volume

• Amount of water

• Density

• Depth

Which principle is related to bouyancy?

• Pascal Principle

• Bernoulli's Principle

• Principal of Bouyancy

• Archimedes' Principle

What is floatation?

• Floatation is when the buoyant of an object allows it to sink or float depending on density

• When water sinks all objects

• A floating object that displaces a weight of fluid equal to its own weight

• The principle that everything that everything will float

An object more dense in fluid will...

• Sink

• Neither sink nor float

• Float

• Fly

What is pressure?

• How much force is being applied on the fluid.

• A force divided by the area over which the force is exerted

• How much volume is in the liquid

• The density of the object on the water

How can we explain Pascal's principle?

• Principle that explains the change in volume exerted by liquid pressure

• The principle that underlies all hydraulic devices and systems

• A significant change in depth that causes the atoms to become closer to one another

• A change in pressure at any point of enclosed fluid at rest is transmitted to all points in fluid

An object that has density that's equal to the density of the fluid

• Neither sink nor float

• Float

• Become buoyant

• Sink

What does Archimedes' Principle state?

• An immersed object is buoyed by a force equal to the weight of the fluid it displaces

• The density of the object immersed in fluid will cause it to neither sink nor float

• While fluid pressure is high then the object put into a liquid will cause it to sink immediately

• There can not be an object that will float while there is high water molecular adhesion

Surface Tension is...

• A property of liquids that makes their surface act like a stretched elastic sheet

• A contractive tendency of the surface of liquids; caused by molecular attractions

• When there is a change in the liquid molecular structure that causes the liquid to have tension between atoms

• The theory that molecules from the surface of a liquid will attract downwards
