Flashcards in Gas Laws ppt...Wait...... was this gas laws????? Deck (25):
1

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

2

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

3

Which law states that when pressure increases volume decreases

Boyle!!

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

4

which law states that when temperature increases volume increase

Charles!!!

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

5

which gas laws states that with temperature increases pressure increases

Gay-lussac!!

B/c volume is the constant (not used)

6

one mole (Gm molecular weight) of gas occupies the volume STP? 1st what is the volume? next whos law?

 22.4L

avogadro's law

7

___ psi = _____ATM =_____ mmHg

14.7

1

760

8

what is boyle's law

P1V1=P2V2

with TEMP held constant volume is inversely proportional to pressure

when pressure increases volume decreases

 

9

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

 

10

who's law shows that we can calculate how long a tank of O2 will last

boyle's

11

what is chares law

V1T2=V2T1

PRESSURE IS THE CONSTANT

volume is DIRECTLY proportional to temp (at Kelvin)

as temp increases volume increases

12

K=????

oC + 273.15 (or just plain 273)

13

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

14

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

15

avogadro's number

6.022X1023

16

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

17

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

18

WHAT IS THE COMBINED GAS LAW

P1V1T2=P2V2T1

19

STANDARD PRESSURE

STANDARD TEMP

STANDARD MOLAR VOLUME

1 ATM = 760 torr = 760 mmHg = 14.7 psi

O0C (273K)

22.71L 0r 22.41L

20

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

21% O2 at seal level = what in mmHg

159

22

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

23

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

24

adiabatic

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