Correct answer: (d) strong, high
Information Booster:
- Tungsten (also known as wolfram) is used for the filament in light bulbs because it has a very high melting point (approximately 3422°C or 6192°F).
- This high melting point allows the tungsten filament to withstand the high temperatures generated when it heats up to produce light without melting or burning out quickly.
- A bulb filament is made of a tungsten metal with a high melting point.
