This occurs to a CPC suit on a molecular level

• A. Degradation
• B. Permeation
• C. Absorption
• D. Adsorption

Answer: (B)

Permeation is the movement of a chemical through a protective clothing material at the molecular level, from the outside surface to the inside surface. In a CPC suit, the hazardous chemical dissolves into the fabric, diffuses through the material, and emerges on the opposite side. This concept explains how long the suit can provide protection before the chemical may reach the wearer, which is captured by permeation rate and breakthrough time. Absorption would mean the chemical is taken into the fabric as a bulk, not necessarily passing through to the inside. Adsorption is the chemical sticking to the surface. Degradation is the chemical breaking down the material itself. Permeation specifically describes the through-material movement at the molecular level, making it the best fit here.
