gas laws 1 Flashcards
boyles law
increasing pressure at constant temp, volume of gas decreases
decreasing pressure with constant temp, volume
expands (boyles)
charles law
volume of ideal gas is proportional to its absolute temp under constant pressure
gas ___ in volume when heated
expands
if temp of a gas doubles, volume
doubles
cuff volume increasing inETT is applying ___ law
charles
gay lussacs law
pressure is directly proportional to temp if volume is constant
temp goes up, pressure goes ___, if volume is constant
up
gay lussacs tank example
as gas Is released, the liquid in tank vaporizes. heat is lost. temp in cylinder falls and pressure drops
avogadro says
at equal temp and pressures, equal volumes of gas contian equal numbers of particles.
the volume of gas is ___ proportional to the number of gas molecules as long as the temp and pressure are constant
directly (avogardros)
at STP, one mole of a gas has a volume of
22.4 L
avogadro’s number =
6.022 x 10^23
avogadro’s number =
6.022 x 10^23
ideal gas law
PV= nRT (n is moles and R is a constant)
R describes the relationship between
temp and kinetic energy
standard temp is
0C or 273.17K
partial pressure
pressure exerted by an individual gas in a mixture
daltons law of partial pressures
states that the total
pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases:
PTotal = p1 +p2 + p3…
if youre giving a percentage go gas somewhere with an atm of 630 (denver), they will get ___ gas
less
calculate mole fraction
divide the number of moles of a gas by the total number of moles in a mixture
relative humidity measures
the saturation of water in air.
if there is a fixed amt of water in the air and the air temp decreases, how does the relative humidity change?
relative humidity will rise until it it reaches 100
the temp at which moisture content in air will saturate the air is
dew point
