Gases Flashcards
(24 cards)
Manometer
device that pressure of a gas sample with V= Ah
- The height = pressure of the gas in mmHg
What level of the atmosphere contains the most atmospheric mass?
Troposphere contains 75% of atm mass
what allows this _____sphere to have 3/4 of the atm mass?
troposphere has 75% of atm mass from gravity
what allows this _____sphere to have 3/4 of the atm mass?
troposphere has 75% of atm mass from gravity
what allows this _____sphere to have 3/4 of the atm mass?
troposphere has 75% of atm mass from gravity
Thermosphere details
200km thick
edge of space
mesosphere detail
1 bar of pressure is there
What is a barometer
a device that measures atmospheric pressure
what is the atmospheric pressure at sea level?
1 atm
Why do we use mercury in a barometer vs water?
it is more dense so the displacement is much less. this allows the barometer to be shorter in height
what liquid is used in a manometer
mercury
Ideal gas law assumptions (2)
assume no interactions between molecules (only elastic collisions)
assume volume of each molecule is negligible
Boyles law IGL interaction
V is inversley proportional to P

Charles law
V is proportional to T
Avogadro’s law
V is proportional to n
STP means what for T and P
T = 273.15
P = 1 atm
Standard molar V
22.4L
What does Dalton’s law of Partail pressure assume?
n is proportional to P
- so you can use either in an equation
