A term describing a loss of fluid that collects slowly causing surface wetting is:

• A. Seepage
• B. Leakage
• C. Weepage
• D. Spillage

Answer: (A)

Seepage describes a slow movement of liquid through porous material or along tiny pathways, so the fluid gradually reaches the surface and wets it. This slow migration is what creates a surface wetting or damp spot without a noticeable leak from a visible opening. Leakage is a more general term for fluid escaping through gaps or cracks and can occur at various rates, while weepage is fluid exiting from a component or seam, often due to internal pressure and appearing at surfaces as small amounts or droplets. Spillage is a rapid, unintended discharge from overfill or mishandling, not a slow migration through material. So the term that best fits a slow collection causing surface wetting is seepage.
