gas law test

Question 1

which properties explain why hydrogen does not float on air

Answer 1

expand, diffuse readily

Question 2

Standard temperature for gases

Answer 2

237 Calvin’s, 0°C

Question 3

Standard pressures

Answer 3

One ATM, 760mmhg, 760 torr, 14.7 psi

Question 4

drinking through a straw

Answer 4

inhale a low-pressure is created in your mouth, the high-pressure pushing down on the liquid pushes the drink to your mouth

Question 5

marshmallow in a vacuum

Answer 5

The marshmallows put into the vacuum chamber a low-pressure is created around the marshmallow there’s a higher pressure inside so it expamds

Question 6

peeps in the microwave

Answer 6

temperature increases volume increases, Charles law

Question 7

egg in the microwave

Answer 7

temperature increases, pressure increases, rigid container bursts, gay Loussac, high pressure inside low-pressure outside

Question 8

what does Bernoullis principal say about moving gases

Answer 8

moving gases creates low pressure, tornadoes and airplanes

Question 9

how does altitude affect pressure

Answer 9

The higher you go the lower the pressure, less pressure in the mountains

Question 10

Boyles law explain what happened to your lungs as you dive and when you come back to the service

Answer 10

The lower you go the more pressure, Lungs compress because the volume goes down, pressure decreases when you go back up volume decreases EXhale or your lungs will explode

Question 11

how do you know when the pressure inside and outside of an object such as a balloon or equal

Answer 11

what a balloon stops expanding the pressures are equal

Question 12

Boyles law

Answer 12

p1 v1= p2 v2
pressure down volume up
marshmallow in a vaccume

Question 13

Charles law

Answer 13

v1/t1= v2/t2
temperature up volume up
rocket, peeps,soap

Question 14

Gay- Lusaac

Answer 14

p1/t1= p2/t2
pressure up temperature up
cloud egg

Question 15

six properties of a gas

Answer 15

expand to fill containers
defuse readily
Weight and pressure on what the touch
Energy is not lost during collisions
Connecticut energy and speed increase in temperature increases
molecules move quickly and far apart

Question 16

in order to get the gas to dissolve into a liquid what two things can you do

Answer 16

increase pressure, decreased temperature

Question 17

what gas is dissolved and beverages such as Coke

Answer 17

carbon dioxide

Question 18

Grahams law

Answer 18

have your gases move more slowly than later gases

Question 19

why do you temperatures have to be converted rather than using Celsius when calculating from Charles to gays law

Answer 19

degrees Celsius does not show a direct relationship between temperature volume and pressure

Question 20

absolute zero

Answer 20

Cold as possible temperature were no motion occurs -273 degrees Celsius, zero Calvin’s

Question 21

percent of oxygen in the air and does this change at high altitude

Answer 21

21%, no the actual present remains the same, pressure is lower

Question 22

what did researchers discover about high altitude and brain function

Answer 22

hi altitude causes dysfunctions in the brain, Gamov creates a higher pressure

Question 23

two ways you can increase the pressure of a gas in a container

Answer 23

heat it up in a rigid container, decreased volume of container

Question 24

pressure as it relates to gases

Answer 24

pressure is the force between molecules as they hit walls

Question 25

cloud in a bottle demo

Answer 25

One bottle is squeezed pressure increases and temperature increases which creates no cloud, as it is released pressure decreases and temperature decreases, they decrease and cause the gas particles to condense

Question 26

how is what happened at Lake Nioss similar to fire estinguisher

Answer 26

filled with CO2 and 1.5 times heavier than air, pushes air out of fire
Robed air of oxygen equals suffocation

Question 27

if you throw a pressurized can in a fire why does explode

Answer 27

Connecticut Energy increases and temperature increases particles move faster and equal a higher pressure

Question 28

why is it different with a balloon if the gas is heated

Answer 28

molecules move faster come volume expands, pressure is the same, stretches until Max amount

Question 29

if you have a piston with 20 mL of air inside and wait on it if you double the temperature what will be the resulting volume

Answer 29

The volume will double, Charles law

Question 30

A piston contains 2 L of air with the pressure of one pressuring down on the top, what will be the volume inside if the outside is increased to two appetizers

Answer 30

decreased to 1 L, Boyles law

Question 31

if two happiness fears of pressure pushing on a piston what will happen to the pressure if the temperature is doubled

Answer 31

if the volume is the same the pressure will double the volume expands and doubles the pressure remains the same

Question 32

how is carbon dioxide used to predict the possibility of volcanic irruption

Answer 32

carbon dioxide equals lower down from the surface, sulfur dioxide equals corruption close

Question 33

for uses of carbon dioxide

Answer 33

fire distinguish her’s, carbonation of soda, photosynthesis, dry ice
