Gas Laws ppt...Wait...... was this gas laws?????
No description yet. This curated deck is ready for daily study.
Card preview (24)
what is the basic formula you need for all gas laws?? it is actually called the combined gas law
P1 V1 T2 = P2 V2 T1
how to remember all the laws and what is involed with them. (this is my way)
way to look at it is what is on the left is not in the law on the right or is better know as the constant in the equation
Which law states that when pressure increases volume decreases
Boyle!! bc there is no temp (or temp is the constant)
which law states that when temperature increases volume increase
Charles!!! b/c pressure is the constant (or not in the equation)
which gas laws states that with temperature increases pressure increases
Gay-lussac!! B/c volume is the constant (not used)
one mole (Gm molecular weight) of gas occupies the volume STP? 1st what is the volume? next whos law?
22.4L avogadro’s law
___ psi = _____ATM =_____ mmHg
14.7 1 760
what is boyle’s law
P1V1=P2V2 with TEMP held constant volume is inversely proportional to pressure when pressure increases volume decreases
during inspiration, the diaphragm pulls down increasing the volume, and the pressure decreases cousing a pressure gradient allowing air to fow into thorax. who law states this is possiable
Boyle’s
who’s law shows that we can calculate how long a tank of O2 will last
boyle’s
what is chares law
V1T2=V2T1 PRESSURE IS THE CONSTANT volume is DIRECTLY proportional to temp (at Kelvin) as temp increases volume increases
K=????
oC + 273.15 (or just plain 273)
the LMA cuff expands in volume when there is and increase in temp, or the ballon filled a fixed any of gas will expand when sitting in a car that is getting hot.
charles volume and temp directly proportional one increases the other does as well
at STP the volume of a mole of an ideal gas is _____L
22.4L some sources also say 22.71 so look for either on test
avogadro’s number
6.022X1023
just to look at and understand avogadro’s law
1 mole of O2 =32g and occupies 22.4L (22.71L) and contains 6.022x1023 molecules
what is Gay-Lussac’s law
P1T2=P2T1 with volume held constant and temp at absolut K pressure is directly proportional to temp as temp increases pressure increases
WHAT IS THE COMBINED GAS LAW
P1V1T2=P2V2T1
STANDARD PRESSURE STANDARD TEMP STANDARD MOLAR VOLUME
1 ATM = 760 torr = 760 mmHg = 14.7 psi O0C (273K) 22.71L 0r 22.41L
what law states that the sum of all the pressures of the gasses in a volume is equal to total pressure
Daltons law of partial pressures
21% O2 at seal level = what in mmHg
159
what is the partial pressure of 30% O2 and 70% N2O when administering anesthesia at sea level? who law is this?
30% O2 X 760mmHg= 228mmHg 70% N2O X 760 mmHg= 532 mmHg daltons law of partial pressures
who law states that gases move at a velocity that is inversely proportional to the square root of the molecular weight of the gas particle
Graham’s law of diffusion (remember this is the denominator of FICK’s law) what what??? dudes
adiabatic
when the state of a gas is altered without exchange of energy with its surroundings
