I'm an expert in the field of chemistry and materials science, and I'm here to provide you with accurate and helpful information. When it comes to the subject of flammability, it's a critical aspect to consider in various applications, from fuel storage to fire safety.
Flammability is a measure of how easily a substance can ignite and burn. Gasoline is well-known for its high flammability, which makes it an effective fuel for internal combustion engines. However, there are substances that are even more flammable than gasoline. One such substance is ethyl alcohol, specifically in its pure form known as ethanol.
Ethanol is a versatile alcohol that is widely used as a fuel, solvent, and antiseptic. It has a lower ignition temperature than gasoline, which means it can catch fire more easily. The ignition temperature of ethanol is around 363 K (about 90°C or 194°F), whereas gasoline has an ignition temperature ranging from 300 to 450 K (about 27 to 177°C or 80 to 350°F), depending on the type.
Another factor that contributes to the flammability of a substance is its vapor pressure. Ethanol has a higher vapor pressure than gasoline, which means it can evaporate more readily at room temperature. This creates a greater concentration of flammable vapors in the air, making it more prone to ignition.
The boiling point of ethanol is significantly higher than that of gasoline, as you mentioned. Ethanol boils at around 351 K (about 78°C or 172°F), while gasoline has a much lower boiling point, typically ranging from 350 to 500 K (about 77 to 227°C or 170 to 441°F). However, the higher boiling point of ethanol does not necessarily make it more flammable. In fact, the volatility of a substance, which is its tendency to vaporize, is more directly related to flammability. Ethanol's higher vapor pressure and lower ignition temperature make it more volatile and thus more flammable than gasoline.
It's also important to note that the flammability of a substance can be influenced by its concentration in air. Ethanol forms flammable mixtures with air over a wide range of concentrations, which further enhances its flammability.
In summary, while gasoline is highly flammable, substances like ethyl alcohol (ethanol) can be even more so due to their lower ignition temperatures, higher vapor pressures, and the ability to form flammable mixtures with air over a broad range of concentrations.

Ethyl Alcohol's boiling point is over 70 degrees higher than gasoline. Meaning that as the temperature increases, gasoline will convert to vapor more rapidly. Vapor is more flammable than a liquid. In this category, gasoline is the more volatile or flammable substance.
