In which direction does airflow typically move?

Airflow typically moves from high to low pressure due to the fundamental principles of physics regarding air movement and pressure differentials. When there is a difference in air pressure between two areas, air will naturally flow from the region of higher pressure to the area of lower pressure in an attempt to equalize the pressure. This principle is applicable in various scenarios, including ventilation systems, natural airflow in buildings, and during the drying process in remediation where moisture removal is involved. Understanding this concept is crucial for effective microbial remediation, as controlling airflow can significantly influence the drying process and the dispersal of contaminants.

The other choices refer to different phenomena that, while related to airflow, do not accurately define the general direction of airflow in terms of pressure dynamics. For instance, air does not inherently move from cold to hot areas; rather, the temperature influences pressure, and this can further affect air movement, but is not a direct cause of airflow direction.
