Chapter 20, Problem 2PS

Interpretation Introduction

Interpretation:

The variation of concentration of $C{O}_2$ in a large city should be predicted on the basis of given average concentration value of carbon dioxide.

Concept introduction:

• Carbon dioxide is one of the major anthropogenic greenhouse gases and its concentration on a large scale, all over the world makes harmful effect to the earth and to the living systems on earth. Its concentration varies in accordance with the changes in season and climate in a particular area.
• Large increase in the number of automobiles, also enhance the concentration of carbon dioxide in a great extent.
• Parts per million (ppm): It is one of the important concentration expressing terms, and which describes grams of solute per million grams of total solutions.

    $\text{ppm}\text{=}\frac{\text{Mass}\text{of}\text{solute}}{\text{Mass}\text{of}\text{solution}}{\text{×10}}^{\text{6}}$
