clay, ice , sugar, muscles

Question 14

What is another name for particle theory?

Answer 14

The kinetic theory of matter

Question 15

What does the particle theory of matter explain?

Answer 15

The particle theory of matter explains why fluids behave the way they do.

Question 16

What are the five points of the particle theory.

Answer 16

1. All matter is made of tiny particles

2.Particles have empty space between them

3. particles are moving randomly all the time

4.particles move faster and spread further apart when they are heated

5. particles attract one another

Question 17

What are the particles like in a liquid.

Answer 17

The particles in a liquid can slide past each other

Question 18

How can the particles move in a solid?

Answer 18

The particles are tightly packed and only vibrate in place

Question 19

How can the particles move in a gas?

Answer 19

The particles in gas have large spaces between them and spread out to fill their container.

Question 20

What are the two types of flow?

Answer 20

Turbulent flow and laminar flow.

Question 21

What is the differences between laminar and turbulent flow?

Answer 21

Turbulent flow is choppy and irregular and laminar flow is smooth and regular.

Question 22

What is eddy?

Answer 22

Its is a slower moving flow that occurs behind an obstacle

Question 23

What is an example of turbulent flow in the human body?

Answer 23

Plaque build up can cause blood to flow turbulently in your body.

Question 24

What are two characteristics of fluids?

Answer 24

1. Fluids don’t have a definite shape
2. Fluids particles are able to slide past each other (able to flow)

Question 25

What is a flow rate?

Answer 25

A flow rate measures the volume of fluid that moves past a certain point in a given amount of time.

Question 26

What are the four factors that can affect flow rate.

Answer 26

1. the type of fluid 2. the force pushing on the fluid 3. the size of the pipe of opening the fluid is flowing through 4. The surface the fluid is flowing over

Question 27

What is VIscosity?

Answer 27

Viscosity is the thickness of resistance to flow

Question 28

What happens to a fluids appearance and Flow rate when it is more viscous

Answer 28

The appearance is thicker and the flow rate is slower

Question 29

What is cohesion?

Answer 29

Cohesion measures how strongly particles are attracted to one another. Cohesion is a reason for viscosity

Question 30

What is surface tension?

Answer 30

Surface tension is the cohesion of a liquid on the surface

Question 31

What is adhesion?

Answer 31

Adhesion measure how strongly particles of a fluid are attracted to another substance.

Question 32

What is an example of turbulent flow?

Answer 32

Water flowing on rocks, waves

Question 33

What is an example of Laminar flow?

Answer 33

Water coming out of a hose

Question 34

What is an example of Laminar flow in the human body?

Answer 34

when the human body is healthy blood will have a laminar flow

Question 35

Why cant solids flow?

Answer 35

Solids are unable to flow because the particle aren't able to move they only vibrate in place which doesn't allow them to flow. Solids also have a definite shape and fluids don't

Question 36

When you tip a bottle of syrup upside down, it take a long time for all the syrup to flow why?

Answer 36

Maple syrup takes longer to flow because it has a higher Viscosity, which means is is a thicker fluid. Maple syrup's cohesion is also higher which means its particles are strongly attracted to one another. The last reason it take maple syrup longer to flow out of its container is because of the adhesion of the bottle to the maple syrup
