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.

Is burning of candel is spontaneous process?
Yes, candle burning is a spontaneous process. A spontaneous process is defined as: once it is allowed to start, the process will proceed to the finish without any external intervention. You lit the candle, it was allowed to burn and it would keep going without any help. The Gibbs free energy change for this process is negative. On the other hand, the decomposition of CaCO3(s) is NOT a spontaneous process. You have to keep heating the reaction vessel in order to decompose all CaCO3. Outside intervention is needed for this process to finish.
Can pomelo peelings be a charcoal?
Pomelo peelings can be used as a natural charcoal since they contain a high carbon content and can be burned to create heat. However, the quality of the charcoal may not be as high as commercially produced charcoal due to variations in the burning process and impurities present in the peelings.
Is the burning of paper a spontaneous reaction?
No, the burning of paper is not a spontaneous reaction as it requires an external heat source to initiate the combustion process. Once the paper is exposed to sufficient heat, it undergoes a chemical reaction with oxygen in the air to produce heat and light energy, resulting in the flame and smoke that we observe during combustion.
Does charcoal have an effect on the ozone layer?
Charcoal itself does not have a direct effect on the ozone layer. However, the process of burning charcoal can release carbon monoxide and other pollutants into the atmosphere, contributing to air pollution which can indirectly impact the ozone layer.
Why is charcoal burning in the grill a chemical change?
Burning charcoal in the grill is a chemical change because it involves a chemical reaction where the charcoal reacts with oxygen in the air to produce carbon dioxide, water vapor, and energy in the form of heat and light. This results in the formation of new substances with different properties from the original charcoal.
Is burning of candel is spontaneous process?

How can I learn how to make drawing charcoal?
You can learn how to make drawing charcoal by researching online tutorials or taking a class on charcoal making. The process typically involves burning wood in a controlled environment to create charcoal sticks that can be used for drawing.
How is charcoal obtained from wood?
Charcoal is obtained from wood by heating it in the absence of oxygen through a process called pyrolysis. This process removes volatile components, leaving behind mostly carbon. The resulting charcoal can then be crushed and processed into different forms for various uses.
Can pomelo peelings be a charcoal?
Pomelo peelings can be used as a natural charcoal since they contain a high carbon content and can be burned to create heat. However, the quality of the charcoal may not be as high as commercially produced charcoal due to variations in the burning process and impurities present in the peelings.
Is burned charcoal acidic or alkaline?
Burned charcoal is alkaline in nature. It has a high pH due to the presence of ash and other alkaline compounds resulting from the burning process.
Why do you need to put a hole in making paper charcoal?
Putting a hole in paper charcoal allows for better airflow, which helps to regulate the burning process and prevents the charcoal from extinguishing. It also helps to release any excess moisture or volatile gases, allowing the charcoal to burn more efficiently.
Is the process exergonic and spontaneous?
Yes, if a process is exergonic, it releases energy and is spontaneous.
Is passive diffusion a spontaneous process?
Yes, passive diffusion is a spontaneous process.
What provides energy to keep a camp fire going?
A campfire is kept going by burning fuel such as wood, charcoal, or propane. The heat generated from the burning fuel then sustains the combustion process and allows the fire to continue burning.
Is the burning of paper a spontaneous reaction?
No, the burning of paper is not a spontaneous reaction as it requires an external heat source to initiate the combustion process. Once the paper is exposed to sufficient heat, it undergoes a chemical reaction with oxygen in the air to produce heat and light energy, resulting in the flame and smoke that we observe during combustion.

Charcoal itself does not have a direct effect on the ozone layer. However, the process of burning charcoal can release carbon monoxide and other pollutants into the atmosphere, contributing to air pollution which can indirectly impact the ozone layer.
How can one determine if a process is spontaneous?
A process is spontaneous if it occurs without any external influence or assistance. One way to determine if a process is spontaneous is by calculating the change in Gibbs free energy (G). If G is negative, the process is spontaneous.
