Pressure
This is a substance that can change shape
Fluid
This is obtained when density is multiplied by the volume occupied by an object
mass
state the type of fluid used in
a hydraulic system
a pneumatic system
liquid
gas
the most common pollutant of water
oil
A substance with a mass of 12g and density of 6g/ml has this volume
2 ml
This is the SI unit of pressure and this is the SI unit of force
Pascal (Pa) and Newton (N)
This is the force that acts opposite the force of gravity and makes an object feel lighter
buoyant force
The brakes of a car are examples of common these systems
hydraulic systems
they are machines like vacuum cleaner that pull up the oil from the surface of the water
skimmers
what is the density of a 2.5 cm3 glass marble that has a mass of 7.5 g?
3
Air pressure can be measured with this device
barometer
According to ........ principle the buoyant force on an object is equal to ......... displaced by the object
the Archimedes' principle
the weight of the fluid displaced
the force exerted by a person on the brake pedal is multiplied and transmitted to the brake pads and then the car stops .The car brakes applies ................... to stop a car
Pascal's Principle
Are large , floating barriers that act like a fence to contain the oil.
Booms
what is the volume of 20 g of a liquid with density equals 1g/ml
20 ml
What happens to atmospheric pressure as elevation increases and this is what happens to water pressure as depth increases?
decreases and increases
This is how you can predict whether an object will float or sink in a fluid
Density
The lift system is an example of this system
hydraulic systems
this method removes 90 percent of the spill
Burning
28 g of iron is added to graduated cylinder containing 45 ml of water. The water level rises to the 49 ml mark. From this information calculate the density of iron.
7g/ml
it is decrease in volume caused by a force
Compression
This is an example of a device that moves fluid by increasing the pressure on the fluid
medicine dropper
air pump
it is a disk that moves inside a cylinder
piston
What is the average cost of cleaning up a fluid spill
between $20 and $200 for every litre
What volume of silver metal will weigh exactly 2500.0 g. The density of silver is 10.5 g/cm3.
238.09
