What is the name for an enclosed space in a building designed to capture and discharge or circulate air?

• A. Plenum
• B. Vessel
• C. Commodity
• D. Ignition Temperature

Answer: (A)

This question is about the term for an enclosed space in a building used to capture and circulate air. That space is called a plenum. A plenum is an air-handling chamber, often the area between a dropped ceiling and the structural ceiling or around ductwork, that collects, discharges, or distributes air through the HVAC system. It can serve as a return path or a supply pathway for air moving through the building. The other options don’t fit: a vessel is simply a container for fluids or gases, a commodity is a good or valuable item, and ignition temperature refers to the temperature at which a material will ignite.
