Efforts to lower SO₂ to mitigate acid rain could worsen global warming by decreasing cooling effects. The concept of mole fraction, important for gas mixture analysis, is introduced along with Dalton's law, which connects partial pressures to mole fractions using hydrogen and oxygen mixtures as examples.

The term refers to any type of atmospheric pollution—regardless of source, composition, or concentration—that creates a significant reduction in atmospheric visibility. Smog encompasses a broad category of air pollutants created through a multitude of processes that relate specifically to the atmospheric conditions of the formation region.

It includes examples like vegetable soup and soil, showing distinct phases within the mixtures. Additionally, smog is mentioned as an inconsistent heterogeneous mixture. The concept of a phase is clarified as a distinct layer, contrasting with pure substances that are single-phase.
