Introduction to Domestic Cooking Gas
Domestic cooking gas primarily refers to the fuel used in household cooking appliances. This gas is commonly supplied in a liquefied form for ease of storage and transportation.
Composition of Domestic Cooking Gas
- Domestic cooking gas mainly consists of liquefied petroleum gas (LPG), which is a mixture of:
- Butane: A four-carbon alkane that is a key component of LPG.
- Isobutane: The branched-chain isomer of butane, also present in significant amounts.
Why Option B is Correct
- Efficiency: Butane and isobutane are efficient fuels that produce a high energy output with relatively low emissions when burned.
- Storage and Transportation: These gases can be liquefied at moderate pressures, making them easy to store in cylinders.
- Safety and Convenience: LPG is odorized for safety, allowing users to detect leaks through a distinct smell.
Comparison with Other Options
- Option A (Methane and Ethane): Although methane is a significant component of natural gas, domestic cooking gas is primarily LPG, not a mix of methane and ethane.
- Option C (Ethylene and Carbon Monoxide): These gases are not typically used for cooking due to their toxic nature and are not part of domestic cooking gas.
- Option D (Hydrogen and Acetylene): While hydrogen is a clean fuel, acetylene is not used for cooking due to its instability and safety concerns.
Conclusion
In summary, the correct answer is option B because domestic cooking gas primarily consists of liquefied butane and isobutane, which are safe, efficient, and practical for household cooking purposes.
