Lt gas laws Flashcards
1
Q
ideal gas law eqn
A
PV=nRT
- at constant T and V, P is proportional to n
2
Q
what’s Boyle’s law
A
P1V1=P2V2
- pressure inversely proportional to volume
3
Q
what’s daltons’ law
A
- each partial pressure of the gas in the dry mixture all add up to the total gas pressure
4
Q
eqn for partial pressure of a gas
A
Pgas= Fgas (fractional share of the gas in the mixture) x total pressure
5
Q
what happens to the barometric pressure if the altitude increases
A
it decreases
6
Q
what is water vapour pressure or humidity
A
- partial pressure of H20 in EQB in condenses state
- depends on temp
- at body temp, its 6kPa
7
Q
what is STPD
A
standard temp(0 degrees celcius ), pressure, (101kPa) dry
8
Q
what is BTPS
A
body temp (37 degrees celcuis) pressure (101kPa), saturated
