Question

a surface with an albedo of 0.10 will:
reflect most sunlight
absorb most sunlight
glow brightly
stay cooler than a lighter surface

Explanation:

Albedo measures a surface's sunlight reflectivity, where 0 = no reflection, 1 = full reflection. An albedo of 0.10 means only 10% of sunlight is reflected, so 90% is absorbed. A lower albedo (darker surface) absorbs more light and becomes warmer than a lighter, higher-albedo surface.

Answer:

Absorb most sunlight
