Gas Laws ppt...Wait...... was this gas laws????? Flashcards

1
Q

what is the basic formula you need for all gas laws?? it is actually called the combined gas law

A

Q

how to remember all the laws and what is involed with them. (this is my way)

A

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

Q

Which law states that when pressure increases volume decreases

A

Boyle!!

bc there is no temp (or temp is the constant)

Q

which law states that when temperature increases volume increase

A

Charles!!!

b/c pressure is the constant (or not in the equation)

Q

what is boyle’s law

A

P1V1=P2V2

with TEMP held constant volume is inversely proportional to pressure

when pressure increases volume decreases

Q

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

Q

what is chares law

A

V1T2=V2T1

PRESSURE IS THE CONSTANT

volume is DIRECTLY proportional to temp (at Kelvin)

as temp increases volume increases

Q

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.

A

charles

volume and temp directly proportional

one increases the other does as well

Q

at STP the volume of a mole of an ideal gas is _____L

A

22.4L

some sources also say 22.71

so look for either on test

Q

just to look at and understand avogadro’s law

A

1 mole of O2 =32g and occupies 22.4L (22.71L) and contains 6.022x1023 molecules

17
Q

what is Gay-Lussac’s law

A

P1T2=P2T1

with volume held constant and temp at absolut K pressure is directly proportional to temp

as temp increases pressure increases

18
Q

WHAT IS THE COMBINED GAS LAW

A

P1V1T2=P2V2T1

19
Q

STANDARD PRESSURE

STANDARD TEMP

STANDARD MOLAR VOLUME

A

1 ATM = 760 torr = 760 mmHg = 14.7 psi

O0C (273K)

22.71L 0r 22.41L

20
Q

what law states that the sum of all the pressures of the gasses in a volume is equal to total pressure

A

Daltons law of partial pressures

21
Q

21% O2 at seal level = what in mmHg

A

159

22
Q

what is the partial pressure of 30% O2 and 70% N2O when administering anesthesia at sea level?

who law is this?

A

30% O2 X 760mmHg= 228mmHg

70% N2O X 760 mmHg= 532 mmHg

daltons law of partial pressures

23
Q

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

A

Graham’s law of diffusion

(remember this is the denominator of FICK’s law) what what??? dudes

24
Q

adiabatic

A

when the state of a gas is altered without exchange of energy with its surroundings

25
