Which term describes an item made or constructed of a material that has no pores or openings and cannot absorb liquids?

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

Answer: (B)

The concept being tested is porosity and absorbency of materials used in esthetics. A material described as nonporous has no pores or openings and cannot absorb liquids. This makes it ideal for sanitation because liquids won’t wick into the surface and can be cleaned and disinfected more effectively. By contrast, absorbent materials soak up liquids, and porous materials have openings that allow absorption. Hydrophobic refers to water-repelling properties, which can apply to various surfaces, but it doesn’t by itself define whether a material has pores. Therefore, the term that precisely fits “no pores and cannot absorb liquids” is nonporous.
