Fluids

Question 1

Anything that flows.

Answer 1

Fluid

Question 2

What are the two types of fluids?

Answer 2

Liquids and gases.

Question 3

The state of matter that has a definite shape and volume. Its particles are close together and the particles can only move from vibrations.

Answer 3

Solid

Question 4

The state of matter that has a definite volume, but its shape is determined by its surroundings. Liquids can slip and slide.

Answer 4

Liquid

Question 5

The state of matter that has its shape and volume determined by its surroundings. The particles of a gas are very fast, far apart, and can go against gravity.

Answer 5

Gas

Question 6

The change from solid to liquid. This is done by adding heat to a solid.

Answer 6

Melting

Question 7

The change from liquid to gas. This is done by adding heat to a liquid.

Answer 7

Evaporation

Question 8

The change from gas to liquid. This is done by removing heat from a gas.

Answer 8

Condensation

Question 9

The change from liquid to solid. This is done by removing heat from a liquid.

Answer 9

Solidification

Question 10

The change of state when a solid turns into gas without first turning into a liquid. This is done by adding heat to a solid.

Answer 10

Sublimation

Question 11

The temperature at which something starts to vaporize rapidly.

Answer 11

Boiling Point

Question 12

What is the boiling point of gold?

Answer 12

2,700 degrees celsius.

Question 13

The temperature at which a substance changes state from a solid to a liquid.

Answer 13

Melting Point

Question 14

What is the melting point of gold?

Answer 14

1,064 degrees celsius.

Question 15

The temperature at which a substance changes state from a liquid to a solid.

Answer 15

Freezing Point

Question 16

What is the freezing point of gold?

Answer 16

1,064 degrees celsius.

Question 17

The “thickness” or “thinness” of a liquid. High viscosity is thick, low viscosity is thin.

Answer 17

Viscosity

Question 18

Name two fluids with high viscosity.

Answer 18

Honey & maple syrup

Question 19

Name two fluids with low viscosity.

Answer 19

Juice & milk

Question 20

The time it takes a fluid to flow from one point to another.

Answer 20

Flow Rate

Question 21

It is hard for the particles in a liquid to pass by each other.

Answer 21

Resistance to Flow

Question 22

Name a fluid with lots of resistance to flow.

Answer 22

Ketchup

Question 23

List five substances that have a low viscosity.

Answer 23

Water,juice,milk,tea,and lemonade.

Question 24

List five substances that have a high viscosity.

Answer 24

Honey, maple syrup, ketchup, gravy, and corn syrup.

Question 25

What is the effect of temperature of a liquid?

Answer 25

Temperature affects the speed at which a liquid flows. Hotter = Less Viscous, Colder = More Viscous
