Are the films dried in or out of the hangers and why?

• A. In the hangers so edges dry slowly
• B. Out of the hangers so edges dry
• C. In the hangers to protect edges
• D. Out of the hangers to keep edges damp

Answer: (B)

Drying is driven by evaporation, which happens fastest where the surface is most exposed to air flow. When films are dried out of the hangers, the edges are freely exposed to air, so moisture evaporates quickly from those outer margins and the edges dry first. The center may stay damp a bit longer, but the important point is that edge exposure accelerates drying. Keeping films in the hangers shields the edges from air, slowing edge drying, and would not keep them damp intentionally as a general rule.
