The mineral graphite has a varying burn point and cant be determined exactly. It has a melt and vaporization point however. Hear I have a little info on graphite...
The mineral graphite is one of the allotropes of carbon. It was named by Abraham Gottlob Werner in 1789 from the Greek γράφειν (graphein): "to draw/write", for its use in pencils, where it is commonly called lead (not to be confused with the metallic element lead). Unlikediamond (another carbon allotrope), graphite is an electrical conductor, a semimetal. Thus, e.g., it is useful in arc lamp electrodes. Graphite is the most stable form of carbon understandard conditions. Therefore, it is used in thermochemistry as the standard state for defining the heat of formation of carbon compounds. Graphite may be considered the highest grade of coal, just above anthracite and alternatively called meta-anthracite, although it is not normally used as fuel because it is hard to ignite.
There are three principal types of natural graphite, each occurring in different types of oredeposit:
- Crystalline flake graphite (or flake graphite for short) occurs as isolated, flat, plate-like particles with hexagonal edges if unbroken and when broken the edges can be irregular or angular;
- Amorphous graphite occurs as fine particles and is the result of thermal metamorphismof coal, the last stage of coalification, and is sometimes called meta-anthracite. Very fine flake graphite is sometimes called amorphous in the trade;
- Lump graphite (also called vein graphite) occurs in fissure veins or fractures and appears as massive platy intergrowths of fibrous or acicular crystalline aggregates, and is probably hydrothermal in origin.
Highly ordered pyrolytic graphite or highly oriented pyrolytic graphite (HOPG) refers to graphite with an angular spread between the graphite sheets of less than 1°. This highest-quality synthetic form is used in scientific research.[3] The name "graphite fiber" is also sometimes used to refer to carbon fiber or carbon fiber-reinforced polymer Graphite

What is ignition temperature for water?
i am for certain that water has a ignition temperature.it will be a very high temperature. eventhough if we attain that temperature,the water will be already in vapor state. we know that like all liquids , water boils when its vapor pressure reaches its surrounding pressure.so we could relate that the boiling temperature is directly proportional to its surrounding pressure. so if we increase the surrounding pressure unbelievably high i.e(vacuum) and try the temperature, we might see water burning.but it's very difficult to attain such a high temperature at present. may be in the future.
What is the ignition temperature of a brick?
The ignition temperature of a brick is typically around 1,000 degrees Celsius (1,832 degrees Fahrenheit). This means that for a brick to catch fire and combust, it would need to be exposed to a flame or heat source at or above this temperature for a sustained period of time.
What elements make up gunpowder?
Oh, dude, gunpowder is like a party mix of ingredients. It's got charcoal to keep things burning, sulfur to add that stinky touch, and potassium nitrate to bring the boom. Mix them all together, and you've got yourself a recipe for some explosive fun!
What problem will be caused if a fuel has an ignition temperature below the average room temperature?
A fuel with an ignition temperature less than the room temperature would spontaneously ignite - it would not be suitable for fuel because it would burn itself up before it could be used to power an engine.
How does charcoal work?
Charcoal works by absorbing impurities and toxins through a process called adsorption, where molecules adhere to the surface of the charcoal. It has a porous structure that increases its surface area, allowing it to trap and remove contaminants from air, water, or the body. Charcoal is commonly used in water filtration systems, air purifiers, and as a detoxifying agent in medicine.
What temperature does it have to be in order for briquettes to glow?
Briquettes are a type of charcoal used when cooking on the grill. These charcoal pieces get so hot that they glow in 400 degree heat.
Is charcoal briquettes on barbecue solid liquid or gas?
Charcoal briquettes are a solid material. When they are burned in a barbecue, they produce heat and light by undergoing a chemical reaction known as combustion, but the briquettes themselves remain in solid form throughout the process.
What element does charcoal briquettes fall under?
Charcoal briquettes fall under the element of carbon. Briquettes are carbonized wood of several different species. Most are made of mesquite.
Can eating charcoal briquettes be harmful to dogs?
Charcoal briquettes are not toxic to dogs. If a dog swallowed a briquette whole, it could become obstructed in the intestines. Self-lighting briquettes contain petroleum products that may cause mild stomach upset if enough is eaten.
Are charcoal briquettes meant to have flames?
Yes, Charcoal Briquettes meant to have flames but more than that they smouldering irons heat up the food into a delicacy
Who invented charcoal briquettes?
Charcoal briquettes were invented by a man in Pennsylvania named Ellsworth Zwoyer. He patented them in 1897 and produced them at Zwoyer Fuel Company.
How can charcoal briquettes be used to reduce humidity in a space effectively?
Charcoal briquettes can effectively reduce humidity in a space by absorbing excess moisture in the air. Placing a bowl of charcoal briquettes in the room can help to absorb the moisture, thus lowering the humidity levels.
What are the easiest lighting briquettes?
Briquettes come in different forms and types. There are biomass briquettes, charcoal briquettes, wood (or sawdust) briquettes, ceramic briquettes and peat briquettes. The ceramic briquettes are most commonly used in gas grills. It appears that the sawdust briquettes are the easiest to light.
Why charcoal is burnt in hearth?
because ignition temperature
What other uses do charcoal briquettes have?
Charcoal briquettes can be used as a fuel source for cooking, heating, and even as a mosquito repellent when burned outdoors. Some people also use charcoal briquettes for absorbing odors in a refrigerator or a room by placing them in a container to help neutralize any unwanted smells.
How hot does a typical box type oven get?
Heat is determined by the number of charcoal briquettes used. One briquette equals 40 degrees Fahrenheit of temperature. So 9 briquettes will equal 360 degrees.
What do carbon pyrolysis wood charbon briquettes have in common?
charcoal
