Chapter 10, Problem 121AP

Interpretation Introduction

Interpretation:

Whether the partial pressure of carbon dioxide in the Northern Hemisphere is higher in summers or in wintersis to be explained.

Concept introduction:

The number of moles and partial pressure are directly proportional to each other. This can be shown by the given equation:

${\chi }_i=\frac{P_i}{P_{\text{total}}}$

Here, ${\chi }_i$ is the mole fraction, $P_i$ is the partial pressure, and $P_{\text{total}}$ is the total pressure.

Carbon dioxide is a colorless gas thatis essential for life.
