Viscosity

Question 1

What is the particle theory of matter? (five main points)

Answer 1

1. All matter is made up of very small particles
2. All particles in a pure substance are the same but are different from a different substance
3. There is space between particles
4. The particles are always moving. They move faster if they gain energy
5. There are attractive forces between the particles. Some strong; some weak.

Question 2

What is viscosity?

Answer 2

-Viscosity is a measure of liquids resistance to flow

Question 3

What is a fluid? (two points)

Answer 3

-Any form of matter that flows
-The states of matter that can be considered fluids are liquid and gases

Question 4

What is the flow rate?

Answer 4

the flow rate is the speed when a fluid flows from one point to another

Question 5

high temperature = ______ viscous

Answer 5

high temperature = less viscous

Question 6

high concentration = ______ viscous

Answer 6

high concentration = more viscous

Question 7

high attractive forces = _______ viscous

Answer 7

high attractive forces = more viscous

Question 8

high particle size = _______ viscous

Answer 8

high particle size = more viscous

Question 9

What are the three states of matter?

Answer 9

solid, liquid, and gas.

Question 11

A liquids shape is ______
A liquids volume is ______
A liquids particle arrangement is ______
A liquids particle movement is ______

Answer 11

A liquids shape is indefinite
A liquids volume is definite
A liquids particle arrangement is close
A liquids particle movement is free flowing

Question 12

A gases shape is ______
A gases volume is ______
A gases particle arrangement ______
A gases particle movement is ______

Answer 12

A gases shape is indefinite
A gases volume is indefinite
A gases particle arrangement is far apart
A gases particle movement is random

Question 13

What does viscosity determine

Answer 13

Viscosity determines the thickness or thinness of a liquid

Question 14

How is a fluid that is viscous described?

Answer 14

it is described as “not runny” or thick

Question 15

what is friction in a liquid?

Answer 15

A force that resists movement

Question 16

how does friction affect how viscous a liquid is?

Answer 16

The more friction the more viscous

Question 17

what are particles like in a fluid that has viscosity?

Answer 17

the particles are holding on slightly to each other
