Which property makes aerogels suitable for thermal insulation in space applications?
- High Density
- Low Thermal Conductivity
- Electrical Conductivity
- Magnetic Properties
Answer: Low Thermal Conductivity
Aerogels are ultra-light porous materials (~99% air) with extremely low thermal conductivity, making them excellent insulators. Used in Mars rovers, spacecraft, and building insulation. India researches aerogels at ISRO and IITs. Critical for materials science and space tech questions.
