Gases Flashcards
atmosphere layers lowest to tallest
troposphere, stratosphere, mesosphere, thermosphere
gas in stratosphere
ozone
when a substance is in liquid state, its entities can only…
undergo vibrational motion
avogadros law
volume of gases at same temp & pressure contain equal # of molecules
charles law
as temp increases, volume increases proportionally when when pressure & amount of gas stay constant
pressure & temp law
pressure exerted by a gas is proportional to temperature in Kelvin
ideal gas law
product of pressure & volume, is directly proportional to number of moles & temp in kelvin of a gas
reactions of gases
when measured at the same temp & pressure, volume of gaseous reactants & products of chem reactions are always in simple whole number ratios
molar volume of gases
the volume one mole of gas occupies at a specific temp & pressure is the same for all gases at the same temp & pressure
SATP & STP
when does the atmosphere come less dense
as height/altitude increase
earths surface
nitrogen 78%
oxygen 20%
ozone 20%
argone 0.9%
CO2 0.036%
what does atmosphere use sun radiation for
turning to thermal energy
what does GHG do
trap infrared radiation
kinetic molecular theory
all substances contain particles in constant random motion
solid- motion
vibrational particle motion
