Is gas and plasma compressible
Yes
No
Is solids and liquids compressible
Strongly agree
Agree
Neither agree nor disagree
Disagree
Strongly disagree
Do your ears pop when going up a mountain or swimming to the bottom of your pool
Yes
No
Does the atmosphere exert pressure all around us?
Yes
No
Pressure is the amount of force applied to a given area
Yes
No
In comparing the flow rate of different engine oils down a ramp, why is it important to test the different types of motor oils?
To determine the density
To determine the proper viscosity for the engine to run properly.
To determine the buoyancy
What situation would increase the viscosity of oil?
When the temperature decreases
When the temperature becomes room temperature
When the temperature increases
What is the formula for Mass
D/V
DxV
V/D
VxD
What is the formula for Volume
D/M
M/D
DxM
MxD
What is the formula for Density
V/M
M/V
VxM
MxV
What is the purpose of Plimsoll Lines on ships?
To show its weight
To show how safely it can be loaded in different water conditions
To show how heavy it will be in different climates during the year
What is the relationship between flow rate and viscosity in a liquid?
They have the same density
The higher the viscosity the lower the flow rate and opposite there inversely related.
There the same
Which floats on top of the other; warm water floats on cold water, or cold water floats on warm water?
Cold on warm because the cold pushes the warm under like how theres water under ice in the winter at rivers/lakes
Warm water floats on cold water because it is less dense therefore it is more buoyant.
Why does a balloon filled with hot air rise?
Because of particles and stuff
Because when heat is collided with a balloon it becomes less dense so it floats
When air is heated the particles separate more making it float because the hot air becomes less dense than the normal air
What is buoyancy
Buoyancy is when density is put with viscosity
The upward force exerted by a fluid is called the buoyant force also known as buoyancy.
What is compression
Compression is the action of being pressed down or squished together with something else
Compression is when you put weight onto the an object
Compression is when you do stuff
What is a plimsoll line used for?
To show what climates it can work in
How safely it can be loaded in different countries
How safely it can be loaded in different water conditions
What is density
Its weight
Density is like another word for weight in an object so lets say a ping pong ball is 0.96 and water is 1.00 the ball will float if the density is lower than the fluid it will sink if it is higher
What is flow rate
Flow rate is how fast liquids move up things
Flow rate is a measure of the speed at which a fluid flows from one point to another the higher the flow rate the lower the viscosity
What is viscosity
Viscosity is the resistance of a fluid to flow different fluids have different viscosity
Viscosity is when you put a fluid on a scale
What is a hydrometer
It measures mass
It measure viscosity
A hydrometer is a device that uses buoyancy to measure the density of a liquid
