Which law describes the dispersion of pollutants in the atmosphere?

The Gaussian plume model is a mathematical representation that describes the dispersion of pollutants in the atmosphere, particularly from continuous sources such as smokestacks or industrial emissions. This model accounts for various factors such as wind speed, atmospheric stability, and the release height of pollutants to predict how these contaminants spread over distance from their source.

The Gaussian distribution assumes that pollutants disperse in a bell-shaped curve, where concentrations decrease with distance from the source. This model is widely used in environmental engineering and air quality assessments because it captures the key dynamics of pollutant behavior in the atmosphere, allowing for predictions about their concentration levels at various locations downwind.

Other options represent different principles but do not specifically focus on air pollutant dispersion. Newton's Law pertains to motion and force, Bernoulli's Principle deals with fluid dynamics and pressure, and Dalton's Law is concerned with the behavior of gases in a mixture, rather than their dispersion characteristics in the atmosphere. All these principles play important roles in physics and chemistry but do not provide the specialized framework for understanding how pollutants disperse in air.
