Chemical vapors from the evaporating solvent in Cutback Coating contribute to smog formation in what conditions?

The correct choice highlights that chemical vapors from evaporating solvents in Cutback Coating are most likely to contribute to smog formation during hot summer conditions. In warmer temperatures, the volatility of solvents increases, leading to a higher rate of evaporation. As these vapors rise into the atmosphere, they can react with ultraviolet (UV) light and other pollutants in the air, facilitating the formation of ground-level ozone, which is a primary component of smog.

Additionally, during hot summer days, atmospheric conditions often lead to stagnant air, allowing pollutants to accumulate and intensify smog formation. High temperatures can also cause chemical reactions between pollutants that may exacerbate smog conditions. Understanding the interplay of temperature, humidity, and sunlight is crucial in identifying the environmental conditions conducive to smog appearance.
