How can you calculate flow rate?
Flow rate (Volume) = volume of fluid passing/time
What is matter?
Matter is anything that has mass and volume (Takes up space)
What is density
DENSITY is a ratio compares mass to volume for a given substance
Is gas a fluid
Yes
What is buoyancy?
Buoyancy is the upward force that a fluid exerts on an object
What is flow rate?
The volume of fluid that passes per unit of time.
can matter be an gas?
Yes
What makes density?
Mass/volume make density
Can fluids have a fixed shape?
No, kinda. occasionally fluids can have a fixed shape but those are in rare occasions.
How do hot air balloons work with buoyancy?
A hot air balloon uses a burner to heat the inside of the balloon allowing it to float thanks to gravity
Describe viscosity
Viscosity is a measure of a fluids resistance to flow.
What are the 3 states of matter?
solid, liquid, gas, (plasma)
When particles are closer together is the density higher?
Yes when particals are closer the density is higher.
Name 3 gas's
Hydrogen, helium, methane (you can name other's)
why do submarines have special designed air tanks
to allow the submarine to rise and sink
would syrup have a high viscosity or a lower viscosity?
Syrup would have a high viscosity rate
What is all matter made of?
All matter is made of atoms
What is displacement?
Displacement is the word used to describe when an object or substance takes the place of another.
Name 1 way to solidify a a liquid and a gas
Freeze it (works if a liquid), for a gas you can condensed it than freeze it making it into a solid.
How do fish adjust to their bouyancy
because of their special bladders
A 50m3 tank was filled tank was filled in 10 minutes. calculate the flow rate.
5m3/min
What is the the difference between the 3 states of matter
Solids have a fixed shape, liquids have a fixed volume BUT take the form of there container, and gas's don't have a definite shape nor volume.
A chocolate bar has a mass of 450g and a volume of 57 cm^3. calculate the density
the density is 7.9g/cm^3
How can you make a solid into a liquid or gas?
apply a large amount of heat to the solid.
What does archimedes principle state?
archimedes principle states the upward buoyant force that is exerted on something immersed in a fluid is equal to the weight of the fluid displaced by the object.
