Concept explainers
(a) Referring to Problem 1.119. calculate the total volume (in liters) of air an adult breathes in a day. (b) In a city with heavy traffic, the air contains
Interpretation:
The volume of air and carbon monoxide intake of an adult, in a day, is to be calculated.
Concept introduction:
A conversion factor is used to convert one unit into another.
The appropriate conversion factor for any equality is selected in such a way that it results in the proper unit cancellation.
The conversion factors for this are
1hr = 60 min. The conversion factors for this are
Answer to Problem 120AP
Solution:
a)
b)
Explanation of Solution
a)
Given information:
Number of breaths per minute is 12. The volume of air per breath of a resting adult is 500 mL.
Explanation:
An adult takes in 500mL of air per breath. The conversion factor for this is
Number of breaths per minute is 12.
1 min = 12 breath
The conversion factor for this is
Multiply
Multiply
Convert volume to liters by multiplying the calculated volume by the conversion factor
Volume of air breathed in a day is
b)
Given information:
Air contains
Explanation:
An adult breathes 8640 liters of air in a day.
One liter of air contains
The conversion factor to find the volume of carbon monoxide is
Multiply
Volume of carbon monoxide is
