Final answer:
The burning of wood is an exothermic reaction and an oxidation process, releasing heat and light during the process.
option b is correct
Step-by-step explanation:
option b is correct The burning of wood is indeed a chemical process, but it is not endothermic; it is exothermic. When wood burns, it undergoes a combustion reaction, which is a type of oxidation process where wood reacts with oxygen from the air to form carbon dioxide, water, and release heat. Therefore, the correct answer to your question is that the burning of wood is B) Exothermic reaction and it is also D) Oxidation process. During this reaction, the system releases heat into the surroundings, resulting in an increase in the temperature of the surroundings. The sign of q (the quantity of heat) for an exothermic process is negative because the system is losing heat. As an example, a campfire is a practical illustration of exothermic combustion, releasing energy in the form of heat and light, useful for various activities like cooking or providing warmth.
An endothermic process is a chemical reaction or physical change that absorbs heat from the surroundings. The burning of wood is an example of an endothermic process because it absorbs heat. During combustion, the wood reacts with oxygen to produce carbon dioxide and water, while absorbing heat energy in the process. This heat energy can be used for cooking, keeping warm, or other purposes.
