gas law test Flashcards
which properties explain why hydrogen does not float on air
expand, diffuse readily
Standard temperature for gases
237 Calvin’s, 0°C
Standard pressures
One ATM, 760mmhg, 760 torr, 14.7 psi
drinking through a straw
inhale a low-pressure is created in your mouth, the high-pressure pushing down on the liquid pushes the drink to your mouth
marshmallow in a vacuum
The marshmallows put into the vacuum chamber a low-pressure is created around the marshmallow there’s a higher pressure inside so it expamds
peeps in the microwave
temperature increases volume increases, Charles law
egg in the microwave
temperature increases, pressure increases, rigid container bursts, gay Loussac, high pressure inside low-pressure outside
what does Bernoullis principal say about moving gases
moving gases creates low pressure, tornadoes and airplanes
how does altitude affect pressure
The higher you go the lower the pressure, less pressure in the mountains
Boyles law explain what happened to your lungs as you dive and when you come back to the service
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
how do you know when the pressure inside and outside of an object such as a balloon or equal
what a balloon stops expanding the pressures are equal
Boyles law
p1 v1= p2 v2
pressure down volume up
marshmallow in a vaccume
Charles law
v1/t1= v2/t2
temperature up volume up
rocket, peeps,soap
Gay- Lusaac
p1/t1= p2/t2
pressure up temperature up
cloud egg
six properties of a gas
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
in order to get the gas to dissolve into a liquid what two things can you do
increase pressure, decreased temperature
what gas is dissolved and beverages such as Coke
carbon dioxide
Grahams law
have your gases move more slowly than later gases
why do you temperatures have to be converted rather than using Celsius when calculating from Charles to gays law
degrees Celsius does not show a direct relationship between temperature volume and pressure
absolute zero
Cold as possible temperature were no motion occurs -273 degrees Celsius, zero Calvin’s
percent of oxygen in the air and does this change at high altitude
21%, no the actual present remains the same, pressure is lower
what did researchers discover about high altitude and brain function
hi altitude causes dysfunctions in the brain, Gamov creates a higher pressure
two ways you can increase the pressure of a gas in a container
heat it up in a rigid container, decreased volume of container
pressure as it relates to gases
pressure is the force between molecules as they hit walls
cloud in a bottle demo
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
how is what happened at Lake Nioss similar to fire estinguisher
filled with CO2 and 1.5 times heavier than air, pushes air out of fire
Robed air of oxygen equals suffocation
if you throw a pressurized can in a fire why does explode
Connecticut Energy increases and temperature increases particles move faster and equal a higher pressure
why is it different with a balloon if the gas is heated
molecules move faster come volume expands, pressure is the same, stretches until Max amount
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
The volume will double, Charles law
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
decreased to 1 L, Boyles law
if two happiness fears of pressure pushing on a piston what will happen to the pressure if the temperature is doubled
if the volume is the same the pressure will double the volume expands and doubles the pressure remains the same
how is carbon dioxide used to predict the possibility of volcanic irruption
carbon dioxide equals lower down from the surface, sulfur dioxide equals corruption close
for uses of carbon dioxide
fire distinguish her’s, carbonation of soda, photosynthesis, dry ice
