Gas laws Quiz supp

Question 1

Van der Waal

Answer 1

Corrects for intermolecular attractions between gaseous and for the finite volume of the gas molecules.

Ideal gases obey gas laws at all temps. and pressures.

There are no ideal gases.

Real gases deviate at high pressure and/or low temps.

Vander Waals Equation deals with this deviation.

Vander Waals relationship assumes that gas molecules have finite volumes and that gas molecules attract one another.

Question 2

Avogrado #

Answer 2

Hypothesis that, at equal temperatures and pressures, equal volumes of gas contain equal numbers of particles. The volume of gas is directly proportional to the number of gas molecules as long as pressure and temperature are held constant.

V1/n1=V2/n2

Question 3

Plethysmography (Application Boyles Law)

Answer 3

The measurement of functional residual capacity

Question 4

Cuff ETT/ LMA (Application of Charles Law)

Answer 4

volume increases with temperature and vice versa

Question 5

4 Quantities that describe the Empirical Gas Laws

Answer 5

1. Pressure
2. Temperature
3. Volume
4. Number of moles.

Question 6

Gay-Lussacs Law

Answer 6

P1 / T1 = P2 / T2

Pressure is directly proportional to temperature if volume is constant.

Temperature goes up, then pressure goes up if volume is constant.

Question 7

H-L-H

Answer 7

if a higher vapor pressure agent is placed in a vaporizer designed for a lower vapor pressure agent, the concentration of the agent will be higher than the dial.

Question 8

L-H-L

Answer 8

if a lower vapor pressure agent is placed in a vaporizer designed for a higher vapor pressure agent, the concentration of the agent will be lower than the dial.

Question 9

Isoflurane Vapor Pressure

Answer 9

760-240= 520 Isoflurane Vapor Pressure (238) 240

520/760= 68.4% Isoflurane
31.6% Oxygen

Question 10

Desflurane Vapor Pressure

Answer 10

760-670= 90 Desflurane Vapor Pressure (669) 670

90/760= 11.8% Desflurane
98.2% oxygen

Question 11

Sevoflurane Vapor Pressure

Answer 11

157

Question 12

Halothane Vapor Pressure

Answer 12

243

Question 13

(Avagadro) 1 Mole of gas =

Answer 13

1 mole = 22.4L ½ mole = 11.2

Question 14

Joules cools

Answer 14

As a cylinder of compressed gas empties, the cylinder cools.
How a cryoprobe works.
N2O tanks

Question 15

Gas Density

Answer 15

Unlike liquids or solids, gas density depends strongly on Temperature and Pressure

Question 16

Distribution of KE

Answer 16

The sum of the kinetic energy and potential energy is the internal energy.

Temperature increase is added energy and increases the average KE of the molecules. Temperature is directly proportional to the average KE
