Answer 4

Spaces

Question 5

The shape of a liquid is determined by …

Answer 5

The volume of its container

Question 6

Matter is ..

Answer 6

Anything that has mass and volume

Question 7

Which of the following statement(s) about thermal expansion are true?

Answer 7

When the temperature of a substance increases, its volume increases and when the temperature of a substance decreases, its volume decreases.

Question 8

Which of the following determines the volume of a gas?

Answer 8

The volume of its container

Question 9

Define viscosity

Answer 9

The thickness or thinness of fluids is a property called viscosity. Viscosity is the resistance of a fluid to flow.

Question 10

True or False: Fluids with a high viscosity flow very fast.

Answer 10

False

Question 11

According to particle theory, particles are constantly in motion. However, when particles have difficulty moving past one another, this is known as …

Answer 11

internal friction

Question 12

Define flow rate

Answer 12

Flow Rate measures the speed at which a fluid flows from one point to another.

Question 13

True or False: When adding heat to a liquid, the fluid flows more quickly.

Answer 13

True

Question 14

True or False: When adding heat to a gas, the fluid flows more quickly.

Answer 14

False

Question 15

True or False: When removing heat from a gas, the fluid flows more quickly.

Answer 15

True

Question 16

True or False: When removing heat from a liquid, the fluid flows more quickly.

Answer 16

False

Question 17

What are the 4 steps that were completed in the “Viscosity Race” lab?

Answer 17

Step One: Making a Prediction
Step Two: Creating step-by-step instructions
Step Three: Making Observations and Recording Results
Step Four: Conclusions and Explanations of Results

Question 18

How does internal friction affect viscosity

Answer 18

the more internal friction there is, the more difficulty particles have passing by each other.

Question 19

What happens when you add heat to a liquid?

Answer 19

The particles start to move faster, which leads to more space between the particles, which leads to less attraction between particles, which means particles flow more easily, which means the liquid is less resistant to flow.

Question 20

What happens when you add heat to a gas

Answer 20

The particles start to move faster, which leads to more collisions and rubbing between particles, which leads to more internal friction, which means particles flow with more difficulty.

Question 21

Are viscous fluids runny?

Answer 21

No

Question 22

What are some examples of fluids with low viscosity?

Answer 22

Water, milk, and juice.

Question 23

What are some examples of fluids with high viscosity

Answer 23

Honey, ketchup, mustard, and toothpaste.

Question 24

Is a fluid with low viscosity thick or thin

Answer 24

thin

Question 25

Is it more difficult for water particles or honey particles to pass by each other?

Answer 25

Honey. Honey has more internal friction.

Question 26

What kind of particles take a long time to pass by each other?

Answer 26

Large particles
