What does absorption value measure in materials?

• A. The strength of a material under pressure
• B. The material's ability to resist heat
• C. The material's ability to accept liquid or gas
• D. The durability of a material over time

Answer: (C)

Absorption value specifically measures a material's ability to accept liquid or gas. This characteristic is critical in various applications, including roofing, where materials must effectively handle moisture and water penetration. A high absorption value can indicate that a material may retain water, which can lead to issues such as mold growth or degradation over time. Thus, understanding the absorption properties of roofing materials helps in selecting the right materials for specific environments, ensuring durability and performance. The other options focus on distinct properties: material strength under pressure, heat resistance, and overall durability over time, which do not pertain to the absorption capabilities of materials. Recognizing how these properties differ from absorption value allows for a more comprehensive understanding of material selection in construction and roofing projects.
