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

Question 1

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

Answer 1

P₁ V₁ T₂ = P₂ V₂ T₁

Question 2

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

Answer 2

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

Question 3

Which law states that when pressure increases volume decreases

Answer 3

Boyle!!

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

Question 4

which law states that when temperature increases volume increase

Answer 4

Charles!!!

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

Question 5

which gas laws states that with temperature increases pressure increases

Answer 5

Gay-lussac!!

B/c volume is the constant (not used)

Question 6

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

Answer 6

22.4L

avogadro’s law

Question 7

___ psi = _____ATM =_____ mmHg

Answer 7

14.7

1

760

Question 8

what is boyle’s law

Answer 8

P₁V₁=P₂V₂

with TEMP held constant volume is inversely proportional to pressure

when pressure increases volume decreases

Question 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

Answer 9

Boyle’s

Question 10

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

Answer 10

boyle’s

Question 11

what is chares law

Answer 11

V₁T₂=V₂T₁

PRESSURE IS THE CONSTANT

volume is DIRECTLY proportional to temp (at Kelvin)

as temp increases volume increases

Question 12

K=????

Answer 12

^oC + 273.15 (or just plain 273)

Question 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.

Answer 13

charles

volume and temp directly proportional

one increases the other does as well

Question 14

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

Answer 14

22.4L

some sources also say 22.71

so look for either on test

Question 15

avogadro’s number

Answer 15

6.022X10²³

Question 16

just to look at and understand avogadro’s law

Answer 16

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

Question 17

what is Gay-Lussac’s law

Answer 17

P₁T₂=P₂T₁

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

as temp increases pressure increases

Question 18

WHAT IS THE COMBINED GAS LAW

Answer 18

P₁V₁T₂=P₂V₂T₁

Question 19

STANDARD PRESSURE

STANDARD TEMP

STANDARD MOLAR VOLUME

Answer 19

1 ATM = 760 torr = 760 mmHg = 14.7 psi

O⁰C (273K)

22.71L 0r 22.41L

Question 20

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

Answer 20

Daltons law of partial pressures

Question 21

21% O₂ at seal level = what in mmHg

Answer 21

159

Question 22

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

who law is this?

Answer 22

30% O₂ X 760mmHg= 228mmHg

70% N₂O X 760 mmHg= 532 mmHg

daltons law of partial pressures

Question 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

Answer 23

Graham’s law of diffusion

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

Question 24

adiabatic

Answer 24

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