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 does the combustion of petrol cause?
The combustion of petrol produces carbon dioxide, water vapor, and heat energy. It also releases pollutants such as carbon monoxide, nitrogen oxides, and particulate matter into the atmosphere.
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 energy is released when petrol burns?
When petrol burns, chemical energy stored in the molecules of petrol is converted into heat and light energy. This is a result of the combustion process, where the carbon and hydrogen in petrol react with oxygen to form carbon dioxide and water, releasing energy in the form of heat and light.
The burning of charcoal is a spontaneous processyet heat must first be applied to start a charcoal why?
The combustion of charcoal is an exothermic reaction: once the reaction starts, it releases heat, making it self-sustaining. However, initially, an external source of heat is required to overcome the activation energy barrier and initiate the reaction. Once started, the reaction releases enough heat to sustain itself.
What does petrol plus oxygen equal?
Add heat and you get combustion.

What energy conversion is happening when charcoal is used the fuel for barbecue.?
When charcoal is used as fuel for a barbecue, chemical energy stored in the charcoal is converted into thermal energy (heat) through combustion. This heat is then used to cook the food on the grill.
What does the combustion of petrol cause?
The combustion of petrol produces carbon dioxide, water vapor, and heat energy. It also releases pollutants such as carbon monoxide, nitrogen oxides, and particulate matter into the atmosphere.
Is burning petrol exothermic or endothermic?
Burning petrol is an exothermic process. It releases heat and light as energy is given off during the combustion of petrol.
What is the energy conversion in a charcoal iron?
In a charcoal iron, the energy conversion involves the chemical energy stored in the charcoal being converted into heat energy through combustion. When the charcoal is ignited, it undergoes a chemical reaction that releases heat energy. This heat energy is then transferred to the metal plate of the iron, raising its temperature and allowing it to effectively press and remove wrinkles from fabric.

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 the heat of combustion for decane?
The heat of combustion for decane is approximately -6,316 kJ/mol. This value represents the amount of heat released when one mole of decane is completely burned in oxygen to form carbon dioxide and water.
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.
