The term "king of gases" doesn't have a single, universally accepted answer within the scientific community. The title is used informally and depends on the context. Several interpretations exist based on the provided references:
1. Sulphur Dioxide (SO2) in Chemistry
According to one reference, sulphur dioxide (SO2) is sometimes referred to as the "king of gases" in chemistry. This likely refers to its historical significance and widespread impact on various chemical processes and industrial applications. However, this is not a standardized or universally accepted scientific term.
2. Brand Names and Commercial Use
Several references mention "King" in relation to various gas-related businesses:
- Gas King Oil Co. Ltd.: This company is a local fuel supplier, illustrating how "King" can be used as a brand name to denote a prominent player in the retail fuel market. This isn't a scientific classification.
- King Soopers Fuel Centers: This grocery chain includes fuel stations, showcasing another example of "King" as a brand name in the fuel industry.
- King LP Gas Services: This company provides various LP gas services, further demonstrating the commercial use of "King" in relation to gases.
These examples show the term "King" applied commercially, not as a scientific designation.
3. Cannabis Strains
One reference mentions "King Louie XIII Gas," a cannabis strain. Here, "Gas" likely refers to the strain's pungent aroma and effect, often associated with a specific type of cannabis terpene profile. This usage is specific to the cannabis industry and doesn't reflect a broader scientific definition.
4. Gas Grills and Appliances
Several references mention "King" in relation to gas grills (Weber, Broil King). These references show that "King" is used as a brand name, designating them as major players in the gas grill market. This doesn't imply a "king of gases" in a scientific sense.
In conclusion, the question is ambiguous. There's no single "king of gases" scientifically. The title is used informally in different contexts, often as a brand name or to highlight a specific gas's historical importance or a particular characteristic (like the strong aroma of a certain cannabis strain).
