|
22.3L
|
|
|
What is the STPD or Molar Volume of All other Gases
22.4L |
22.4L

|
What is vapor vs gas?
|
Vapor is below its critical temp
Gas is above its critical temp |
|
|
What is vapor?
|
The transition state between a liquid and a gas during which through the application of pressure/Temp changes-the transition may be reversed.
|
|
|
What is Gas?
|
A fluid state of matter with the least organization and definition.
|
|
|
Define Absolute Humidity
|
The amount or content of "water Vapor" which is humidity, that is in a gas.
|
|
|
Define Relative Humidity
|
The capacity of a gas to hold humidity or the water vapor at a given temperature.
The temperature changes the capacity to be held and is expressed as a % percent. |
|
|
At 37o C normal body temp and and 100% relative humidity and 760 mm hg of standard pressure...
What is the water vapor content? What is the water vapor pressure? |
44 mg/L
47 mm hg |
|
|
What is gas saturated?
|
When relative humidity = 100%
|
|
|
Define critical Temperature?
|
Above this temp gas cannot be converted back to a liquid at any pressure and below this temp. pressure can be used to compress a gas back to liquid state.
-118o C for O2 |
|
|
Define Critical Pressure
|
Pressure required to convert a gas to a liquid state at its critical temp.
716 PSI for O2 |
|
|
Define Boyle's Law
|
When Temp is held constant...when pressure is added volume is reduced and when pressure is less volume increases.
|
|
|
Define Charle's Law:
|
When pressure is held constant...Temp increases and decreases with the volume.
Temp increase so does volume...temp decreases so does the volume. |
|
|
Define Gay-Lussac's Law
|
When Volume is held constant...increase in temp. increase in pressure. Decrease in temp-decrease in pressure.
|
|
|
Define Avogadro's Law
|
Equal volume of gas at the same temp and pressure...have the same number of moles.
|
|
|
Define Henry's Law
|
Weight of gas dissolving in a liquid is proportional to the partial pressure of the gas above the liquid.
|
|
|
How many more times is co2 more diffusible than o2 in the blood?
|
19 times more
|
|
|
Define Fick's Law
|
Gases diffuse from areas of high concentration to areas of low concentration and at a rate proportional to the concentration gradient.
|
|
|
What is the Bernoulli's principle?
|
As the forward velocity of a gas is increased its lateral pressure decreases with corresponding increase in pressure.
|
|
|
Define Jet?
|
An opening that uses a jet like effect and increases velocity..Pressure gauge will have a negative effect. It will be a cap like devise on the end of a tube. It entrains the air from outside in the jet to mix with oxygen.
