The burning of charcoal is a spontaneous process yet heat must first be applied to start a charcoal why?
Burning charcoal is spontaneous, but not at room temperature. To start the combustion energy must be added (in the form of heat). Once the temperature of the charcoal reaches a certain temperature it reacts exothermically and releases heat. This heat of reaction is sufficient to locally heat more charcoal so that it burns continuously.
What happens when charcoal burns?
The carbon (the main component of charcoal) is oxidized, releasing heat, which is why it is called a fuel. There are other flammable components in charcoal that also are oxidized, adding their bit to the energy release.
What is the experimental molar heat of combustion?
The experimental molar heat of combustion is the heat released by the total combustion of a substance, determined in a calorimeter.
What is NCV means in the coal industry?
NCV means Net Calorific Value. The lower calorific value or Net calorific value (NCV) which supposes that the products of combustion contain the water of combustion to the vapor state. The heat contained in this water is not recovered.
Is heat of combustion a chemical property of matter?
Heat of combustion is a chemical property of matter.
What does petrol plus oxygen equal?
Add heat and you get combustion.

How does heat combustion of paraffin compare to heat combustion of propane?
how does the heat of combustion of propane compare to the heat of combustion of paraffin wax
What is the heat of combustion of natural gas?
Natural gas is not just one type of hyrdocarbon, and so its heat of combustion (or enthalpy of combustion) will vary from sources. However, it is primarily formed from methane which has a "heat of combustion" of 889 Kilojoules per mole, you could use that value. Hope that's what you wanted!

What is calorfic value?
Its the heating value of the fuel.So actually its the amount of heat or energy realeased during fuel combustion.
What is the heat of combustion for decane?
The heat of combustion for decane is 6779 kJ / mol. Heat of combustion increases with chain length of alkanes.
What is the experimental molar heat of combustion?
The experimental molar heat of combustion is the heat released by the total combustion of a substance, determined in a calorimeter.
Difference in GCV and UHV of coal?
GCV, gross calorific value, is the quantity of heat produced by combustion. UHV, useful heat value, is the gradation of non-coking coal.
Why does the water gas has a high calorific value?
The water gas has a high calorific value because it produces immense heat during its combustion.
Why does water gas has a high calorific value?
The water gas has a high calorific value because it produces immense heat during its combustion.
