As a subject matter expert in the field of physical chemistry, I can provide an in-depth analysis of the question at hand. The question is whether methane is heavier or lighter than air. To answer this, we must first understand the concept of density and how it relates to the comparison of gases.
Density is defined as the mass per unit volume of a substance. When comparing the density of gases to air, we are essentially comparing the mass of a given volume of the gas to the mass of an equal volume of air. The density of air at standard temperature and pressure (STP) is approximately 1.29 g/L. This value is often used as a reference point when discussing the relative heaviness or lightness of other gases.
Methane (\(CH_4\)) is the primary component of natural gas and is also the simplest hydrocarbon, consisting of one carbon atom bonded to four hydrogen atoms. At STP, the density of methane is about 0.717 g/L, which is significantly lower than the density of air. This means that methane is lighter than air under these conditions.
The reference to natural gas and liquefied petroleum gases (LPG) in the provided information seems to be a bit misleading. While it is true that LPG, which includes propane and butane, is heavier than air and can collect in low places, this does not apply to methane. LPG is heavier because it has a higher molecular weight due to the presence of more carbon and hydrogen atoms in its molecules compared to methane.
It is important to note that the behavior of gases can be influenced by various factors, including temperature and pressure. Under different conditions, the density of a gas can change. However, at STP, methane remains lighter than air.
In terms of safety, the fact that methane is lighter than air has implications for its dispersion in the environment. If methane is released into the atmosphere, it will tend to rise and disperse more quickly than a gas that is heavier than air. This property can be both a benefit and a challenge. It is a benefit because it can help to prevent the buildup of methane in confined spaces, reducing the risk of explosions. However, it is also a challenge because it means that methane can contribute to the greenhouse effect when it reaches the upper atmosphere, where it can trap heat more effectively than in the lower atmosphere.
In conclusion, methane is lighter than air, with a density of approximately 0.717 g/L at STP, which is less than the density of air. This characteristic plays a significant role in its behavior in the environment and has both positive and negative implications for safety and climate change.

Natural gas (methane) is lighter than air. ... This gas is more commonly called L.P., bottle gas, propane, butane and various other trade names. Liquefied petroleum gases are all heavier than air and will collect in low places when not confined.
