3. In physics and engineering, the measure of how much thermal radiation is absorbed by a material rather than reflected or transmitted
The thermal absorption coefficient determines the material's effectiveness as an insulator.
O coeficiente de absorção térmica determina a eficácia do material como isolante.
This is a technical term predominantly used in scientific, engineering, and industrial contexts in both Brazil and the USA. It is fundamental in discussions about building insulation, materials science, and environmental engineering. The term is standardized across Portuguese-speaking regions with no significant variations, reflecting the universal nature of physics terminology.
