Fluids and Viscosity
This is caused by the forces of adhesion to the side of the container.
meniscus
the attraction between the particles of one substance to another substance is
Adhesion is
A real life example of buoyancy is
quadski, oil spills, whale adaptions, life jackets
Pressure is measured by
force divided by area
This term describes the behavious of solids, liquids and gases.
Particle Theory of Matter
the amount of space occupied by an object is...
Volume
Compression is...
What is viscosity?
Weight is measure in
Newtons
This is the formula for calculating density
What is D = m/v?
This is the upward force on an object exterted by the surrounding fluid
What is buoyancy?
.... systems use pressurized liquid for mechanical motion and have a higher energy density and higher working pressures.
Hydraulics system
2 factors affecting viscosity are..
friction, cohesion, adhesion, temperature, concentration or particle size?
Density is
is how much matter is crammed into a certain volume.
High density means less particles: true or false
false
An example of buoyancy in real life is
This law states pressure exerted at one surface of an incompresible fluid is equal to the pressure exerted on any other surace
What is Pascal’s law ?
The definition of cohesion is...
Cohesion is the attractive force between water molecules of the same substance.
volume of fluid passing divided by time
Mass is measured in..
grams or kilograms
Float
Some examples of pneumatic systems are
air compressors, air brakes on bikes,trains, or trucks, and pneumatic drills (jackhammers)
