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
liquid
The phase change from a gas to a solid or back, without going through a liquid state
Sublimation
A substance with a mass of 12g and density of 6g/ml has this volume
2 ml
This is the SI unit of pressure
Pascal (Pa)
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
A substance that cannot be broken down into smaller pieces or changed into another substance
element
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 the weight of the fluid displaced by the object
the Archimedes' principle
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
A type of mixture that looks like only one thing
homogenous
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
decreases
This is how you can predict whether an object will float or sink in a fluid
Density
A nail gun would use this type of system
pneumatic system
In a solution, this is what a substance is dissolved in.
Solvent
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
In our floating and sinking experiment, the little plant pot _________
Floated
it is a disk that moves inside a cylinder
piston
The word that describes particles that do not mix with water
Hydrophobic
