Which term describes an item with no pores or openings?

• A. Porous
• B. Absorbent
• C. Nonporous
• D. Hydrophobic

Answer: (C)

Nonporous describes a surface with no pores or openings. Because there are no tiny holes, liquids and microbes don’t get absorbed, making the surface easier to clean and sanitize—an important factor in esthetics. This is why it’s the best term for an item with no pores. Porous would mean it has openings that can absorb or trap liquids; absorbent emphasizes the ability to soak up liquids, which implies pores; hydrophobic refers to water-repelling properties but doesn't by itself guarantee a lack of pores.
