What does CNG stand for?

Answer: A — Compressed Natural Gas

CNG stands for Compressed Natural Gas, which refers to natural gas that has been compressed to less than 1% of its volume at standard atmospheric pressure. This compression process allows for the efficient storage and transport of natural gas, making it viable as an alternative fuel for vehicles, especially in the transportation sector. Natural gas, primarily composed of methane, is a fossil fuel that burns cleaner than gasoline or diesel, producing fewer greenhouse gas emissions. The use of CNG in vehicles contributes to reducing air pollution and decreasing dependence on oil. Understanding the definition and implications of CNG is crucial for drivers operating vehicles powered by this fuel type, as it highlights the benefits and importance of transitioning to cleaner energy sources. The other terms presented do not accurately describe the composition and application of CNG, reinforcing the selection of Compressed Natural Gas as the correct answer.
