10[blank_start]Molecular activity[blank_end] is the movement of molecules and the atoms of which they are made up is constant but not uniform; speed, direction, and movement can vary.
- AMolecular activity
11When gases are compressed, the sum of molecular forces occurs in a closed container and is called [blank_start]cylinder pressure[blank_end].
- Acylinder pressure
12A full E cylinder of [blank_start]oxygen[blank_end] measures 2,200 PSIG while a full E cylinder of [blank_start]nitrous oxide[blank_end] measures 745 PSIG.
- Aoxygen
- Bnitrous oxide
13What gas law says that with temperature as a constant, gas volume varies inversely with pressure.
- ABoyle's Law
- BCharles's Law
- CGay-Lussac's Law
14What gas law is "With volume as a constant, the pressure of a gas is directly proportional to the temperature?

- BGay-Lussac's Law
- CCharles' Law
15Which gas law describes the basis for breathing?

19If you have a 100-liter volume of gas at 273K, which exerts a pressure of 1000 pounds per square inch (psi), and doubling the temperature causes a fourfold increase in pressure, what will be the new volume of gas?
- A100 liters

- AGraham's law of diffusion/effusion
- BFick's Law of Diffusion
- CBernoulli's Principle
- DPouiseille's Law
22Fick's Law of Diffusion tells us that at the start of inhalational anesthesia, delivered concentration is [blank_start]high[blank_end] compared to the blood concentration. As the anesthetic proceeds, the pressure difference falls and the rate of diffusion into the blood [blank_start]slows[blank_end].
- Ahigh
- Bslows
23Henry's Law states that: At a constant temperature, the amount of a gas dissolved in a liquid is [blank_start]directly proportional[blank_end] to the partial pressure of the gas in equilibrium with the liquid.
- Adirectly proportional
24There are two main areas in anesthesia where we utilize Henry's law: calculation of the amount of [blank_start]02[blank_end] in the blood and calculation of the amount of [blank_start]C02[blank_end] in the blood.
- A02
- BC02
25Dalton's law of partial pressures states that the total pressure of a mixture of gases is the [blank_start]sum[blank_end] of all its individual (partial) gas pressures. The total pressure will always equal the atmospheric pressure ([blank_start]760[blank_end] torr, or mm Hg), depending on the altitude.
- Asum
- B760
26[blank_start]Unsaturated[blank_end] solutions permit the addition of more solute while [blank_start]saturated[blank_end] solutions do not allow the addition of more solute without some of the solute precipitating out. An exception is heating the solvent, which allows for the addition of more solute, producing a [blank_start]supersaturated[blank_end] solution.
- Asupersaturated
- BUnsaturated
- Csaturated
27In a water molecule, the electrons are shared unequally with oxygen. Oxygen is slightly more [blank_start]negative[blank_end] and hydrogen is slightly more [blank_start]positive[blank_end].
- Anegative
- Bpositive
28What is the movement of solute and solvent across a permeable membrane at an area of high to low concentration?

- CActive transport
29If two fluids exert the same osmotic pressure, they are said to be [blank_start]isotonic[blank_end].
- Aisotonic
30Hypertonic solutions have a higher amount of solutes than blood, which causes the RBCs to [blank_start]shrink[blank_end].
- Ashrink
