Respiration Modeling (Unit 6 Standard B)

According to Boyle’s law, if the volume of a gas increases,

• The pressure of the gas will increase

• The pressure of the gas will decrease

• The solubility of the gas will increase

• The solubility of the gas will decrease

Which of the following is not a common unit used to describe gas pressure:

• Millimeters of mercury (mm Hg)

• Torr

• Mole (mol)

• Pounds per square inch (psi)

 Directly proportional means…

• if one variable increases, the other decreases

• if one variable decreases, the other decreases

• if one variable increases, the other quadruples

• none of the above

Liquids tend to resist compression because

• Electrons of adjacent atoms tend to attract one another

• Electrons of adjacent atoms tend to repel one another

• Electrons of adjacent atoms remain in fixed positions

• None of the above

The air we breathe is most closely represented by a mixture of

• Nitrogen, carbon dioxide, water and oxygen

• Nitrogen, carbon dioxide, and oxygen

• Nitrogen and oxygen

• Oxygen only

Dalton's Law states…

• that at a constant temperature, the volume of an ideal gas varies inversely with its pressure.

• how gases tend to expand when heated

• that the total pressure exerted by the mixture of gases is equal to the sum of the partial pressures of each individual gas

• that the density of an ideal gas at constant pressure varies inversely with the absolute temperature of the gas.

What is the formula for Henry's law?

• S1 + S2 / P1 + P2

• S1 / P1 = S2 / P2

• T1 / V1 = T2 / V2

• P1V1 = P2V2

Which law is not directly related to the process of external respiration in humans?

• Boyle’s Law

• Dalton’s Law

• Charles’ Law

• Henry’s Law

What is the formula for Boyle's Law?

• P1V1=P2V2

• P1V1/P2V2

• P1V2=P2V1

• P1/V1=P2/V2

 Which of the following is the most soluble gas out of the options below?

• Carbon dioxide

• Oxygen

• Nitrogen

• None of the above
