100
What are the three states of matter
Solid, Liquid, Gas
100
Name two Elements
Gold, Silver etc
100
What is the flow rate and give an example of a fluid with a fast flow rate
how fast a fluid flows from one point and water or perfume
100
Which three states of matter compress the most and why others can't compress
Gas can compress the most, others can't compress because of the little space between particles
100
Give an example of buoyancy
Wood, Hot air balloon, Blims etc
200
What does this symbol mean
Flammable
200
Where do you find the elements
THe periodic table of elements
200
What is density
THe mass per unit volume of a substance
200
Two examples of gas compression in life
Air in airbags
Air in tires
200
Name two factors that affect the dissolving rate
Heat by heating up the particles and making them speed up
Stirring by speeding the up around each other
300
What is one parts of the model of matter
Everything is made of particles, particles always moving, spaces between particles, attractive forces, particles in a pure substance are the same.
300
What is a compound and list a characteristic
Made of two or more elements, lose their individual characteristic when they combine, have strong chemical bonds
300
Name the three states of matter and order them from most to least dense
Solid most dense
Liquid second most dense
Gas is third most dense
300
How does pressure change with altitude
Going up makes less air particles push down on you
but when you go down there is more air particles pushing down on you
300
Two examples of pneumatics in everyday life
Brakes on truck
Dentist drills
Air gun
Dirt tamper
Jack hammer
400
what are some of the characteristics of gas
no definite shape, no definite volume, most not affected by gravity, particles are spread far apart.
400
What is a homogenous solution and name an example
a Homogenous solution is a solution where you cant see the individual parts and have strong chemical bonds, examples are sugar water, tea, orange juice no pulp
400
What is buoyancy
If an object floats and sinks in water
400
What are hydraulics
hydraulics are liquids under pressure and it works by applying liquid pressure and it transmits force to move something else
400
What is archimedes principle
where the force pushing up on an object is the same as the weight of fluid displaced by the object
500
what does this symbol mean and is the inside or the outside hazardous
Poison and the inside is hazardous
500
What is a solute and a solvent and give an example of the two
the solute is whats being dissolved and water is whats the salt is dissolving in
500
What is viscosity and which has more viscosity water or honey
How thick a fluid or how thin a fluid is and answer honey
500
What is pneumatics
Gas under pressure and decompresses the gas and make the particles more apart suddenly creating a steady force to perform tasks
500
Name exceptions to density rules
Ice
Mercury
