Fluids

Question 1

What is a fluid?

Answer 1

A fluid is any substance that flows, this includes liquid and gasses. Fluids don’t have a fixed shape, instead it’ll take the shape of its container. Ex: Water in a cup

Question 6

Whats a example of a slurry IRL

Answer 6

Hydroseeding, the water holds seeds, fertilizer and its sprayed into dirt to grow plants

Question 7

Whats the purpose of a water cytoplasm in a cell

Answer 7

it holds the organelles and provides a medium where they can float, grow function and move

Question 8

A watery cytoplasm is a example of what 5 major things

Answer 8

Hold other materials

Question 9

an irl example of a thing that holds materials is a —-

Answer 9

TOOTHPASTE! It holds materials that cleans, polishes and protects you teeth

Question 10

How can fluids become solids?

Answer 10

A fluid takes shape of its container, like concrete, it can be molded before it hardens

Question 11

Whats a example of a lubricant and what does it do?

Answer 11

Oil, oil is used to reduce friction, noise and heat. Paint, it provides a barrier and protects the wood yk?

Question 12

Whats a example of a fluid used to support?

Answer 12

Air, air in tire! the air supports the tires

Question 13

Whats fluid mechanics

Answer 13

The study of fluids and how they behave

Question 14

Whats fluid dynamics

Answer 14

The study of fluid behavior when in motion

Question 15

Whats the diffrence between fluid mechanics and dynamics

Answer 15

They are BOTH the study of fluids, but mechanics is how it behaves, dynamics is how its in motion

Question 16

What are the 2 areas fluid dynamics can be devided in, and whats is it

Answer 16

1. Hydrodynamics-study of liquid motion Aerodynamics-study of gaseous motion

Question 17

What are the 5 particle theory of matter

Answer 17

1. All matter is made of tiny particles
2. Particals have empty spaces between them
3. particals are moving randomly at ALL time
4. Particals move faster and spread out further when they are heated
5. particals are attracted to each other

Question 18

Whats it called when liquid goes to gas

Answer 18

vaporization

Question 19

Gas-liquid

Answer 19

Condensation

Question 20

Liquid-solid

Answer 20

freezing

Question 21

solid-liquid

Answer 21

melting

Question 22

gas-solid

Answer 22

deposition

Question 23

solid-gas

Answer 23

sublimation

Question 24

Carbon dioxide is a fluid, so is water vapor and lava

Answer 24

ok

Question 25

without blood in ur body what would happen

Answer 25

you wouldnt be able to gather materials to cells nor get the cells waste and transport it out

Question 26

The three states of matter either have deinite shape or volume or not, name witch (Sorry for spelling but idgaf)

Answer 26

Solid- Definite shape and volume Liquid- No deffinite shape but definite volume Gas- Neither it has NO DEFINITE SHAPE OR VOLUME

Question 27

True or false, all states of matter have mass and take up space

Answer 27

true!

Question 28

Gasses true or false, have alot of energy

Answer 28

True

Question 29

Whats energy level in the 3 states of matter

Answer 29

Solids have very little energy Liquids have a medium ammount of energy Gas has ALOTTTTTTT

Question 30

This is either solid liquid or gas: Particles are tightly packed, Force of attraction is so strong that the particles vibrate a very small distance and they cant slide past each other

Answer 30

Solid

Question 31

This is either solid liquid or gas: loosly packed particals, farther appart than solids. particals move freely around eachother BUT the force of attraction is strong enough to hold the _______ together

Answer 31

Liquid

Question 32

This is either solid liquid or gas: Particles move freely they are the FARTHEST appart than any other state, and the force of atrraction is really small

Answer 32

GASSSSSSSSSSSSSS

Question 33

Fluids are what 2 states

Answer 33

Liquid and Gas, dont think its just liquid

Question 34

Fluids can flow because the particles in liquid and gasses can move ______________

Answer 34

Freely

Question 35

What are the two types of flows, and define it

Answer 35

Laminar Flow A smooth regular flow (Example: Lazy river, a flow from the tap, BLOOOOOOOOOD hehe) Basically laminar means their is less resistance and friction, resulting in it avoiding energy loss and drag Turbulent Flow A ROUGH and irregular flow of fluids (Example: HURRICANE, water flow in a river, water rafting, blood clots in arteries)

Question 36

Define flow rate

Answer 36

the measure of how quickly fluids flow

Question 37

What unit is flow rate measured in

Answer 37

Volume/time or L/s

Question 38

Flow rate depends in 4 things

Answer 38

Type of fluid, forces, size of opening, type of surface (if its rough its more friction, slower flow)

Question 39

Whats visocsity and give example of a viscous and thin liquid

Answer 39

A fluids viscosity is the measure of how easily a fluids partical can slide past eachother. Thicker fluids like maple syrup are far more viscous than thinner, like soy sauce, this makes them have more resistance to flow, flowing slower

Question 40

Factors Affecting Viscosity and Surface Tension (2)

Answer 40

Cohesion: How strongly particles in a liquid stick together. More viscous (thicker): Honey, ketchup Less viscous (thinner): Oil, water, soy sauce Ketchup has stronger attraction between particles than oil, making it flow slower Surface Tension: The force that holds liquid particles together at the surface. Water striders stay on water because the force of attraction between water molecules is stronger than gravity pulling them down.

Question 41

Whats adhesion

Answer 41

Adhesion is the attraction between the particles of one substance and a different substance.

Question 42

Ex and why it happens

Answer 42

Milk sticking to a glass even after you've finished drinking. Water forming a meniscus in a graduated cylinder. Why: Adhesion happens because water molecules are attracted to other surfaces, like glass. This is why water spreads out on glass but forms droplets on wax paper (less adhesion).

Question 43

How do u mesure flow rate? whats the unit

Answer 43

Flow Rate= Time (seconds) devided by Volume of Liquid (mL or L) ​Unit: mL/s or L/s

Question 44

Whats something that control water flows?

Answer 44

DAMS!

Question 45

Impact on dams

Answer 45

Loss of lands due to flooding, impact fish population, contribute to bacteria growth and release chemicals in water.
