Ans: Carbon and its compounds, such as hydrocarbons, are used as fuels for several reasons:
- High Energy Content: They release a significant amount of energy upon combustion.
- Abundance: Carbon-based fuels are abundant and easily accessible.
- Variety: They exist in various forms (solid, liquid, gas) which are suitable for different applications.
- Combustion: They combust readily and produce heat, making them efficient for energy generation.
