Final answer:
Hamdan's low-cost aerogel can be used for insulation in buildings, providing thermal protection for spacecraft, and aiding in oil spill cleanup due to its excellent thermal insulation, high absorbency, and lightweight characteristics.
Step-by-step explanation:
The possible uses of Hamdan's low-cost aerogel include insulation in buildings, thermal protection for spacecraft, and aiding in oil spill cleanup. Aerogels provide excellent thermal insulation, which makes them suitable for reducing energy needs in well-insulated buildings by trapping still air within their structure. In the context of space exploration, aerogels offer protection against extreme temperatures. Additionally, due to their high absorbency and light weight, aerogels are effective in cleaning up oil spills by absorbing the oil while floating on water.
