Which statement about natural gas is true?

Explanation:
Natural gas is mainly methane and exists as a vapor under ordinary conditions. Its vapor density is about 0.6 relative to air, which means it is lighter than air and tends to rise and disperse rather than pool as a liquid. In standard natural gas service, you’re dealing with a gas stream, not a liquid, so there is no liquid phase present in normal operation. That’s why the statement describing natural gas as having a vapor density near 0.6 and no liquid is the correct one.
