What is flow rate?
How much a fluid resists to flow.
The speed at which a fluid flows at. It is measured in volume per unit time, like mL/s.
How much mass is in an object per a given area. It is measured mass per volume, like g/ml
It is the behaviour of how a fluid moves.
Surface tension is the cohesion of particles on a liquid's surface.
False. Surface tension is the adhesion of particles on a liquid's surface
True
False. It is the density of a liquid's surface
Which of the following is the measurement of the amount of matter in an object
Density
Mass
Volume
Weight
Select the right answers. Which of the following are methods to find the volume of an object
Formula (length x width x height)
Formula (length + width + height)
Water displacement in a graduated cylinder
Water displacement in an overflowing can
Air displacement in a bucket
20 mL of a unknown liquid has a mass of 140g. The container holding the unknown liquid has a mass of 60g. What is the density of the liquid?
0.4g/mL
0.4
4g/mL

Why would a ship sail lower in freshwater than in cold seawater?
Freshwater is more dense, causing the difference in density (between the freshwater and the ship) to be less than in cold seawater. This causes the winter temperate seawater to be farther from neutral buoyancy than freshwater, causing the ship to sail higher in freshwater.
Freshwater is less dense, causing the difference in density (between the freshwater and the ship) to be greater than in cold seawater. This causes the winter temperate seawater to be closer to neutral buoyancy than freshwater, causing the ship to sail lower in freshwater.
There is more air in the shell of the ship when floating in cold seawater, causing it to float higher
What is a hydrometer
A device that measures density of fluids
A device that measures density of liquids
A device that measures density of gases
A device the measures volume of substances
What does Pascal's law state?
When an object is placed in water, the water level rises
Pressure applied to an enclosed system is spread out evenly throughout the system
There should be no speeding when driving
When a object is placed in water, the volume of the air changes
Why are liquids less compressible than gases?
Liquids contain more particles per given area and the particles are closer than gases, so they can't be pushed much closer.
Gases' particles are closer together than liquids, causing it to be less compressible
There are more gases in the the world, causing it to take up more space in the world
Gases are actually less compressible than liquids
What is air pressure and where would it be lower?
It gets lower closer you are to the ground.
Air pressure is pressure applied to an object because gravity is affecting the air particles above the object. It gets lower the higher you ascend.
Air pressure is pressure applied to an object because gravity is affecting the water particles above the object. It gets lower the higher you ascend.
Air pressure is pressure from the air.
Why may heating up a can of compressed air be dangerous?
Particles spread once you heat it up, but since it is in an enclosed space, there is no place for the particles to go. That causes pressure the build up and the can to possibly explode
The air would explode inside the can.
The particles would start jumping and escape the can. Then the world would become poisoned.
The particles would spread out when heater. Since there is no where for the water particles to go, pressure would build up and the can would explode
