Which form of coal burns the hottest?
Anthracite coal burns the hottest among the various forms of coal. It has a high carbon content and burns with a clean blue flame, making it a popular choice for heating purposes.
What is kerosene oil?
Kerosene is a thin clear liquid formed from hydrocarbons obtained from fractional distillation of petroleum. The process of distilling petroleum into kerosene was first written about in the 9th Century in Persia. By the 1700's it was known as a byproduct of making coal gas and coal tar, but it burned with a smoky flame and was not for use indoors. In 1848 a Canadian discovered a new process and made a fuel for lamp oil which burned bright and clear
Why coal does not produce Flame?
Coal does not produce a visible flame because it needs a high amount of heat to ignite and burn. When coal is heated, it first releases volatile gases which can be lit to produce a flame. The coal itself then burns with a red glow due to the heat generated from the burning gases.
Why do observe a flame initially when wood or coal burns and glow later on?
The flame is produced by gasses coming out of the fresh wood/coal. Once the gasses are exhausted one is left with just the carbon and this does not gassify as it combusts and therefore just glows.
Why do you have to use paper are kerosene oil to start fire in wood or coal?
Paper and kerosene oil are commonly used to start fires because they are flammable materials that ignite easily and create a strong initial flame. Paper provides a quick burst of heat to ignite the wood or coal, while kerosene oil is a liquid fuel that can help sustain the fire until the wood or coal catches fire properly.

Why does burning of candle produce flames and burning of coal cannot?
First of all we will have to know that what is a flame made up of,a flame is made at a point where fuel and oxygen combine,so in case of both candle and coal there is a fuel ie.wax in candle and coal is itself a fuel.................but if we just think till this much then even coal should produce flame but it doesn't go like this ,actually we are missing something ie. hydrogen(the main component in every flame producing substance).........if hydrogen is not there flame will not be produced .So wax has hydrogen atoms whereas coal doesn't because coal has been burnt before and hydrogen has been used.................that is why hydrogen containing waxy candle produces flames whereas already burnt coal just gives heat not flames. Hope this helps.
What is very hard rock that burns with a high heat and little smoke formed from granite?
The rock you are referring to is anthracite coal. It is a type of coal that is very dense, high in carbon, and burns with a clean, hot flame. Anthracite coal is formed from the metamorphism of sedimentary rock, such as bituminous coal, over millions of years.

What is the hardest and oldest type coal?
Anthracite is the hardest type of coal.
Which coal is burned with the least flame?
anthracite coal
What is the texture of coal?
The texture of coal is a 'hard, shiny, black rock. However, the 'hardness' and the 'shininess' can vary depending on the impurities present. However, it is always black. The texture of coal can vary from Peat, )A black wet earth) coal in its early stages of formation. (Burns/combusts with a lot of smoke) Then Lignite ; a soft black rock, with no wetness. ( burns/combusts with less smoke). Then coal as described above ( burns/combusts with a hot bright flame, dependent on the amount of oxygen draught present). Finally Anthracite ; hard and shiny ( Sometimes known as 'Black Diamond'( burns/combusts with a hot bright bluish flame, dependent on the amount of oxygen draught present).,
