The Quest (11/19/15)

Question 1

Define pressure

Answer 1

A force exerted over a certain area

Question 2

What is pressure measured in?

Answer 2

Pascals

Question 3

How is force found?

Answer 3

pascals times area

Question 4

What does Pa stand for?

Answer 4

Pascals

Question 5

What does ATM stand for?

Answer 5

Atmosphere

Question 6

What does Psi stand for?

Answer 6

Pounds per square inch

Question 7

What does thin air mean?

Answer 7

Less dense

Question 8

Where does thin air occur?

Answer 8

Higher Elevations

Question 9

Describe Boyle’s law

Answer 9

Boyle said that with constant temperature, the volume of a gas is inversely proportional to its pressure

Question 10

Describe Charles’ law

Answer 10

With constant pressure, temperature and volume are directly proportional

Question 11

Describe Gay-Lussac’s law

Answer 11

Constant volume, pressure and temp of a gas are directly proportional

Question 12

Give and example of each law

Answer 12

Boyle- bubble under water, the higher up, the less pressure. Less pressure allows for a bigger bubble
Charles- Hot air balloon, the hotter the fluid, the more volume
Gay-Lussac- Pressure cooker, higher the temperature the more pressure

Question 13

Define fluid

Answer 13

any substance that has flow, typically gases or liquids that can be manipulated by pressure, forces, or barriers.

Question 14

How do fluids travel?

Answer 14

areas of high pressure to areas of low pressure

Question 15

How do curves affect the flow?

Answer 15

faster travel over curved surfaces

Question 16

Describe fluid principles

Answer 16

fast fluid, low pressure
Fast moving (high velocity) fluids create areas of low pressure

Question 17

Give some examples of fluid principles

Answer 17

The Attack of The Shower Curtain, the strip of paper, ping pong ball and hair dryer

Question 18

What is Pascal’s principle?

Answer 18

When pressure is exerted anywhere in a confined, incompressible fluid, that pressure is transmitted equally in all directions inside a system

Question 19

What are some examples of Pascal’s principle?

Answer 19

Squeezing and bottle, Hydraulics (only for liquids), Squeezing toothpaste

Question 20

What happens if a gas gets inside a hydraulic system?

Answer 20

The force will jot be exerted.

Question 21

What is Archimedes principle?

Answer 21

The upward boyant force that is exerted on a body immersed in a fluid (fully or partially submerged) is equal to the weight of the fluids that the body displaces.

The weight of the fluid in the spillover bowl will be equal to the buoying force on the object in the larger spout cup.

Question 22

What is bouyancy?

Answer 22

the tendency of an object to float

Question 23

What is density?

Answer 23

mass of an object divided by its volume
