Final answer:
The connection between filaments and thermal stability can be seen in the operation of incandescent light bulbs and the maintenance of cell structure in biology.
Step-by-step explanation:
The connection between filaments and thermal stability can be observed in various contexts, such as the operation of incandescent light bulbs or the maintenance of cell shape and structure in biology.
In the case of incandescent light bulbs, the filament inside the bulb is made of a material with high electrical resistance, typically tungsten. When the bulb is first energized, the filament heats up rapidly due to the flow of current. As the temperature of the filament increases, its resistance also increases, which leads to a decrease in the current flowing through the filament. This helps ensure that the filament reaches a stable operating temperature and prevents it from overheating.
In biology, the intermediate filaments play a role in maintaining cell shape and resisting tension forces. These filaments, made of proteins such as keratin, are intermediate in thickness between microtubules and microfilaments. They provide mechanical support to cells and help anchor organelles together. By resisting tension, intermediate filaments contribute to the overall thermal stability and structural integrity of cells.
