Flight Physiology

Question 1

Boyle’s Law

Answer 1

the volume of a given mass of gas varies inversely with the pressure when the temperature is kept constant.

Question 2

Charle’s Law

Answer 2

the volume of a given mass of gas varies directly with the absolute temperature of the gas when pressure is kept constant.

Question 3

Gay-Lussac’s Law

Answer 3

the pressure of a given mass of gas varies directly with the absolute temperature of the gas, when the volume is kept constant.

Question 4

Graham’s Law

Answer 4

The rate of effusion of a gaseous substance is inversely proportional to the square root of its molar mass.

Question 5

Dalton’s Law

Answer 5

the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of the gases in the mixture.

Question 6

Henry’s Law

Answer 6

“At a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.” An equivalent way of stating the law is that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid:

C=kPgas(1)
