______ is used in buildings and in manufacturing processes to prevent heat loss or heat gain.
Insulation
The correct answer is Insulation.
Cellulose: Made from recycled paper products, often blown into cavities. Aerogel: Highly effective but often more expensive, used in specialized applications. The effectiveness of insulation is often measured by its R-value, which indicates its resistance to heat flow. A higher R-value means better insulating performance.
