Chapter 1, Problem 1Q

(a)

Interpretation Introduction

Interpretation:

The volume of air in liters that might inhale while sleeping for 7.5 hours has to be calculated.

Concept Introduction:

Volume is the amount of space occupied by the matter.

The unit of volume is expressed in milliliters (mL), centimeter cubed (cm3).

(a)

Expert Solution

Explanation of Solution

Assume each breath has a volume of about 0.5L and breathing about 10 times per minute.

The volume of air in liters can be calculated as:

  0.5L1breath×10breath1min×60min1hr×7.5hr=2250L

The volume of air in liters that might inhale while sleeping for 7.5 hours is 2250L.

Therefore, breathing is exposed to a large volume of air.

(b)

Interpretation Introduction

Interpretation:

Five things that improve the quality of air have to be given.

Concept Introduction:

Quality of air refers to a condition in which air in the surrounding. Good air quality refers to the condition of air with less pollution, clear air and free from smog.

(b)

Expert Solution
Check Mark

Explanation of Solution

Quality of air refers to a condition in which air in the surrounding. Good air quality refers to the condition of air with less pollution, clear air and free from smog.

Five things that improve the quality of air is,

  • • Burning of wood, vegetation, fuels etc should be reduced.
  • • Low emission paints which pollute less have to be used.
  • • Vehicles with good silencer have to be used.
  • • Residential areas can improve the air quality by regular cleaning of carpets etc.
  • • Proper treatment before the emission of gases from the industries.
