Gas quiz

Question 1

what do you collisions of molecules resulting

Answer 1

no loss of energy

Question 2

are there attractive forces between molecules

Answer 2

nope

Question 3

properties of a gas

Answer 3

The expansion of a molecule is directly related to the temperature, gas is always expand to fill a container, easily compressed come exert pressure, diffuse readily

Question 4

low-pressure

Answer 4

created by cooling gas molecules, removing gas molecules, increasing elevation, decreases volume

Question 5

high-pressure

Answer 5

created by heating, adding gas molecules, decreasing elevation, increases volume

Question 6

pop can demo

Answer 6

low-pressure is created by cooling the water vapor quickly in the beaker of ice water, high pressure on the outside of the can curse the can

Question 7

candle demo

Answer 7

heating gas molecules but gases are trapped, gases are trapped in there is a moment like what goes in the flask

Question 8

Armstrong line

Answer 8

Little pressure makes the fluids beat up and Bible, pressure is low so vapor releases

Question 9

peep demo

Answer 9

vacuum turns on the molecules in the speed up and make the people bigger high-pressure in the peep low-pressure in the container H2O goes out

Question 10

balloon demo

Answer 10

The air in the balloon increases into the brush pressure inside more than outside the modules expand and speed up inside the balloon, high-pressure in the balloon low-pressure in the container

Question 11

shaving cream demo

Answer 11

The pressure is lowered inside makes the mall to speed up in the shaving cream expense, low pressure on the inside of the container high-pressure in the shaving cream

Question 12

Air pressure

Answer 12

Standard air pressure at sea level

Question 13

standards of air pressure

Answer 13

760 MmhG
760 torr
One ATM
14.7 pounds per square inch
0°C or 270° K

Question 14

pink fountain demo

Answer 14

heating up the steam when flipping strong to the icewater what’s a crate low-pressure
low-pressure inside the balloon high-pressure in the water and phenolphthalein

Question 15

Melvin the balloon

Answer 15

hi in the container low in the balloon, low-pressure cooling molecules in the container hi in the balloon

Question 16

egg demo

Answer 16

high pressure pushes the egg inside the container, low-pressure uses gas molecules and flame goes out molecules cool and create low-pressure.egg is blown out of container

Question 17

Will hydrogen float on air demo

Answer 17

fill a pipe that with air the other pipette with NAO H and aluminum, put them together ignite

Question 18

benoulls Principle

Answer 18

moving gas molecules create low-pressure

Question 19

blow dryer demo

Answer 19

Low pressure due to moving air, high pressure pushes on the low pressure area keeping the ping-pong in the pocket

Question 20

what holds water up demo

Answer 20

when the paper stuck to the test tube the pressures were equal, the paper only stayed with half the test tube filled

Question 21

what is Bends

Answer 21

A person stays at a depth of 100 feet for a certain amount of time and some of the nitrogen from the compressed air dissolved in the water in the body so if the diver swim to the surface too fast it’s painful

Question 22

how is Bends prevented

Answer 22

The driver must rise slowly and make stops on the way up

Question 23

how can Ben be cured

Answer 23

The only cure is to enter a pressurized chamber where the pressure matches that of the deck

Question 24

oxygen poisoning

Answer 24

breathing 100% oxygen gas

Question 25

negatives of oxygen poisoning

Answer 25

decreases gas exchange, chest pains

Question 26
