Unit C
pressure: the amount of force applied to an given area
force: push or poll act on an object
Fluids
Any substance that flows
liquid
gas
viscosity
temperature
matter
Anything that has mass and volume
particle theory of matter
density
all matter are made up by particles
all particles are in constant motion
all particle in a substance are identical
temperature affect the speed which particles move
particle in solid and liquid are more close and have more attraction to each other
lower:
Gas: higher(less friction)
liquid: lower(particle theory of matter
the residence of a fluids to flow
compresstion
decrease of volume caused by a force
mass: how much things are in the matter
volume: the space that the matter take up
how much mass are in a given volume
higher than a fluid: sink, equal to a fluid: in the middle, lower than a fluid: float
Solid>Liquid>Gas (Water>ice) (Particle theory of matter)
friction: the force that works to slow down motion
gravity: the downward force add on a object
buoyancy: the tendency of an object is a fluid to rise or sink due to the density of the surrounding
buoyant force: the upward up exerted by a fluids
Archimedes' principle: the buoyant force on a n objects is equal to the weight of the fluid displaced by the object.
a fluids will always go from low pressure to high pressure
higher
liquid: higher
gas: lower( friction)
compressibility: the property of being able to be compressed
incompressible: solids, liquids
compressible: gas
fluids system
a group of fluids functioning together as a whole.
Pascal's law
when force is applied to an enclosed fluid, the increase in pressure is equally transmitted to all part of the fluid
Hydraulic system: a system that uses liquid to transmitted pressure because liquids cannot be compressed
pneumatic system: a system that use gases usually air.
hoist: use two piston of different size to create pressure to lift vehicle
piston: a disk moves inside a cylinder
Gas need to be compressed in order to be used
pump: a device that move fluids through or into something
valves: a device that control the flow of fluids
fluids spill
oil spill
bioremediation
burn
skimmer
boom
dispersant
sorbents
