Concrete will absorb and radiate stored heat. Which two actions describe how concrete handles stored heat?

• A. Reflect and Insulate
• B. Absorb and Radiate
• C. Store and Release
• D. Transmit and Cool

Answer: (B)

The idea being tested is how concrete uses its thermal mass to manage heat. Concrete can store heat because it absorbs energy when it’s warm and then releases that energy when it cools, helping to even out temperature fluctuations. So the two actions that describe how concrete handles stored heat are absorbing heat and radiating that heat away as it cools. Reflecting would bounce heat off rather than store it, insulating slows or stops heat flow rather than storing/releasing it, and transmitting and cooling describes moving heat through the material rather than its storage and release behavior.
