Question 3

what is a slurrie

Answer 3

a mixurte of sand and water to make transporting stuff easier

Question 4

What are the most important properties of fluids?

Answer 4

viscosity, density, buoyancy, and compressibitly

Question 5

what is the difference between a pure substance, a mechanical mixture, and a solution?

Answer 5

a pure substance is something with only one thing in it. a mechanical mixture is something that you can see all the parts in the mix and a solution is something that has lots of things in it but it looks like there is only one thing in it.

Question 6

what is meant by a contraction of a solution

Answer 6

the contraction fo a solution is a

Question 7

What’s is properties of fluids

Answer 7

Any matter that can flow has no fixed shape and can shape to a container

Fluids become solids

Fluids hold other materials

Question 8

types of fluids

Answer 8

gas and liquids

Question 9

matter

Answer 9

Matter can be hard, soft, rough, smooth, round, hot or cold. Matter is what makes up the universe

Question 10

pure sunstance

Answer 10

Ex. Sugar is made up of only one kind of matter. Can’t be separated into different substances

Question 11

mixurte

Answer 11

Such as soil is made up a combination of different substances sometimes can be separated into different substances

Question 12

mechinal mixurte

Answer 12

You can see the different substances that make up a mixture

Question 13

heterogenous mixurte

Answer 13

You can’t see the different substances that make them up. These mixtures may be solution, suspensions or colloids

Question 14

solution

Answer 14

Look as if it’s one substances also known as a homogeneous mixture

Question 15

homogenous

Answer 15

Looks as one substance but actually two or more

Question 16

suspenison

Answer 16

Is a cloudy mixture in which droplets or tiny pieces of one substance are held within another substance

Question 17

Colliod

Answer 17

Is also a cloudy mixture but the droplets or tiny pieces are so small that they do not separate easily

Question 18

solute

Answer 18

The substance that dissolves

Question 19

solvent

Answer 19

The substance that does the dissolving

Question 20

Concentration

Answer 20

Of a solution tell you the amount of solute dissolved in a specific amount of solvent

Question 21

unstaurated solution

Answer 21

an unstaurated solution is one in which more solute can dissovle

Question 22

saturated solution

Answer 22

a saturated solution is a solution in which no more solute can dissovle at a given temperature

Question 23

what three factor does soubility depends on

Answer 23

the type of solute, the type of solvent and the temperature

Question 24

solubility

Answer 24

the maximum amount of solute you can add to a fixed volume of solvent at a given temperature

Question 25

saturation point

Answer 25

every solution has a satuation point at a given temperature

Question 26

how do you know what has a higher contration

Answer 26

a solution has 50g of solute dissolved in 100ml of water this read 50g/100ml if something said 75g/10ml you would know that has a higher concentration

Question 27

how much salt is the maxium you can add to water?

Answer 27

35.7g

Question 28

solubitiy changes with temperture

Answer 28

solubity increases as the temperuture of the solvent increase

Question 29

What is viscosity? why is it an important propterty?

Answer 29

How quickly fluids flow is a proptery called viscosity. Fluids with high viscosity do not flow as easilty as fluids with low viscosity

Question 30

how does tempurate affect viscosity

Answer 30

As the temperature of the liquid increases its viscosity decreases. The opposite is also true. As the temperature of a liquid decreases its viscosity increases.

Question 31

what does density measure

Answer 31

Density measures the amount of matter in a given volume

Question 32

How do you find the denisty of an object

Answer 32

D= m over v or D=M/V

Question 33

describe pascal’s law and give example of it’s appliction

Answer 33

P= f/a
F= newten 
A-= m2

Pascals law States that an enclosed fluid transmits pressure equally in all directions.
Hydraulic systems

Question 34

how does a car lift work

Answer 34

I device uses to pistons of different sizes to create pressure and to lift the car. A piston is a disc that moves inside of a cylinder. The small piston is the input piston, which pushes down on the liquid to create pressure. This pressure is been transmitted through the liquid work pushes of the large Princeton which is the output piston.

Question 35

As the temperuture of the water rises what happens to it’s density

Answer 35

A substance has a greater density and it’s solid state then it liquid state and gas state. So the hotter the water the lower the density

Question 36

bouyant force

Answer 36

What an object is in a liquid, the force of the gravity pulls it down. The liquid exerts an opposite force called the buoyant force

Question 37

How does detergent clean grease off clean?

Answer 37

detergents use surfactants to carry away dirt

Question 38

what is a pipeline “pig” and how does it move?

Answer 38

a pipeline pig relies on the flow of the fluid to move it through the pipeline
