Why are synthetic fabrics more flammable than natural fabrics?
Synthetic fabrics are more flammable than natural fabrics because they are made from petroleum-based materials such as polyester or nylon, which are essentially plastic. When these fabrics catch fire, they melt and stick to the skin, causing more severe burns. In comparison, natural fabrics like cotton or wool burn more slowly and have a lower combustion rate.
What is the most flammable out of gas and diesel?
Gasoline is the most flammable between gas and diesel due to its lower flash point and vaporization rate. Diesel is less flammable because it requires higher temperatures to ignite compared to gasoline.
What wood is the least flammable?
Hardwoods such as oak, hickory, and maple are less flammable than softwoods like pine and spruce due to their higher density and lower resin content. Dense woods with low sap content like cherry and walnut also tend to be less flammable.
What is the difference between hazardous and flammable gas?
Capable of igniting and burning is a combustible gas. Any compressed gas meeting the requirements for lower flammability limit, flammability limit range, flame projection,etc. All flammable substances are surely combustible, but all combustible substances are not essentially flammable.
Which gas combinations contribute most to combustibility of passing gas?
The main gases in passing gas are methane, hydrogen, and carbon dioxide. Methane is highly flammable and contributes the most to the combustibility of passing gas. Hydrogen is also flammable but in lower concentrations in gas. Carbon dioxide is not flammable.
Will flammable gas concentration above the upper explosive limit burn?
No, flammable gas concentrations above the upper explosive limit (UEL) are too rich to ignite and burn. In order for a flammable gas to ignite, it needs to be within its flammable range, which lies between the lower and upper explosive limits. Concentrations outside this range will not burn.
What is UEL?
All of natural gas has LEL which means lower explosive limit and UEL upper explosive limits mean if lower or upper value for any gas found you get explosion.
What is lel uel?
All of natural gas has LEL which means lower explosive limit and UEL upper explosive limits mean if lower or upper value for any gas found you get explosion.
When is atmosphere containing a flammable gas ignitable?
An atmosphere containing a flammable gas is ignitable when it falls within a specific concentration range known as the flammable or explosive limits. This range is defined by the lower explosive limit (LEL), below which the concentration is too low to ignite, and the upper explosive limit (UEL), above which there is insufficient oxygen for combustion. Additionally, an ignition source, such as a spark or open flame, must be present for ignition to occur. Proper safety measures are crucial to prevent ignition in environments with flammable gases.
What temperature can gasoline still give off flammable vapor?
The FR (flammable range) of gasoline is 1.4% LEL (lower exposive limit) to 7.6 UEL (upper exposive limit). Below 1.4% the gasoline vapor is said to be too lean and above 7.6% and the vapor is too rich. In either case gasoline will not burn if it is not in the FR.

Is ether or gasoline more flammable?
Ether is generally more flammable than gasoline. It has a lower flash point, meaning it can ignite at a lower temperature, and its vapors can easily ignite in air. Additionally, ether's high volatility contributes to its ability to form flammable mixtures more readily than gasoline. Therefore, while both are flammable, ether poses a greater fire hazard.
Does the midpoint of a frequency distribution class equal the sum of the lower and upper limits?
No, the midpoint is the result of adding the upper and lower limits in a class and dividing that by 2. Essentially the mid point is the average of the two limits.
Whats The difference between a 6 and 7 string guitar?
There is practically no difference. The 7-string guitar has one lower string that the 6-string does not. It is usually tuned to B(natural).
What is class limit according to statistics?
The lower and upper limits of a class interval are known as Class Limits.
What is the most flammable out of gas and diesel?
Gasoline is the most flammable between gas and diesel due to its lower flash point and vaporization rate. Diesel is less flammable because it requires higher temperatures to ignite compared to gasoline.
