A) pressure

B) volume

C) temperature

D) mass - Correct answer-A) pressure

Dalton's law states "the total pressure of a mixture of gases equal..."

A) inverse proportional to volume

B) nearly proportional to its absolute temperature

C) inversely proportional to the absolute mass

D) the sum of the partial pressures exerted by the individual gases in the mixture -

Correct answer-D

The largest percentage of the dry atmospheric composition is:

A) oxygen

, B) carbon dioxide

C) nitrogen

D) hydrogen - Correct answer-C) nitrogen

To calculate the partial pressure of a gas rate at a certain altitude, the following

points must be known:

A) barometric pressure and temperature

B) barometric pressure and rate of ascent

C) temperature and gas concentration

D) gas concentration and barometric pressure - Correct answer-D) gas

concentration and barometric pressure

According to Dalton's law, hypoxia results at high altitudes because:

A) decreased temperature make oxygen less available

B) as barometric pressure decreases, oxygen concentration decreases.

C) while oxygen concentration remains unchanged, decreased partial pressure

makes is less available.
