Science Chapter 9

The chapter discusses the principles and applications of compressibility in gases and liquids, emphasizing how increased compression leads to higher pressure due to intensified particle collisions.

9.5

Any increase in particle collision can make the pressure rise
compressability
Gasses compress more than liquids
Dangers of compression
The particles start to move aster, hitting the can which can cause it to explode.
More compression means more pressure

9.7

circulatory system is a closed hydraulic system
Veins have valves

some people have valves that don't close, causing the area to backup and swell

like one way gates that stop blood from pooling and backing up

Fluid filled and closed
Valves
car engines use valves to allow fuel to enter and exhaust to exit

Car engines are also known as international combustion engines

the heart has four valves to help force blood in one direction

keep blood flowng

9.4

Pressure
Fluids exert pressure

Atmospheric pressure

Deep sea divers withstand high pressure with suits

decreases the higher you ascend

The force the atmosphere exerts

The force per unit area
Pascal's law

buses

Hydraulic breaks

Open and close doors

forces applied to fluids distribute equally

Pneumatic power
Can be used to lift heavy loads

allow kneeling buses to let passengers enter and exit quicker.

Hydraulic rams
work by forcing fluid into either side of a piston allowing powerful movement

Some systems use a combination of both systems

Can lift heavy loads

Animals can use this power too

archer fish use hydraulic power to shoot water
