When a match is struck what form of energy does the burning match give off
When a match is struck, it undergoes a chemical reaction known as combustion. During combustion, the matchstick's tip is heated, causing the reactive chemicals on the match head (such as sulfur) to ignite. This chemical reaction releases energy in the form of heat and light. Therefore, the burning match gives off thermal (heat) and radiant (light) energy.
When a match is struck, it undergoes a chemical reaction called combustion. During this combustion process, the burning match gives off several forms of energy, including:
1. Thermal Energy: The most noticeable form of energy released by a burning match is thermal energy or heat. The friction from striking the match against the rough surface of the matchbox ignites the match head, initiating the combustion reaction. As the match burns, it releases heat energy into the surrounding environment.
2. Light Energy: Another form of energy given off by a burning match is light energy. The flames produced by the combustion reaction emit light, making the match visibly glow. The color and brightness of the flame can vary depending on the specific chemicals present in the match head, such as sulfur or phosphorus.
3. Chemical Energy: The burning match also releases chemical energy. Matches typically contain a combination of chemicals, including sulfur, phosphorus, and an oxidizing agent like potassium chlorate. When the match is struck, these chemicals react with oxygen in the air, releasing stored chemical energy.
It's worth noting that while the burning match emits heat, light, and chemical energy, it also releases by-products such as smoke and carbon dioxide into the air.
When a match is struck, the burning match gives off several forms of energy, including heat and light. The process of the match burning involves a chemical reaction between the match head and the striking surface. Here's how it works:
1. Friction: When the match head is dragged across the striking surface, the friction between them generates heat.
2. Activation energy: The heat generated during friction raises the temperature of a chemical compound called phosphorus sesquisulfide, present in the match head.
3. Combustion: As the temperature rises, the phosphorus sesquisulfide begins to decompose, releasing highly reactive molecules. These molecules react with oxygen in the air, initiating a combustion reaction.
4. Heat energy: The combustion of the phosphorus sesquisulfide releases a significant amount of heat energy. This is the main form of energy given off by the burning match. The heat energy warms up the surroundings and can be felt when you hold your hand close to the flame.
5. Light energy: In addition to heat, the burning match also emits light energy in the form of a flame. The heat causes the compounds in the match head to create glowing particles or soot that emit light when they are heated to incandescence.
So, in summary, when a match is struck, it gives off heat energy and light energy through the combustion of the chemical compounds in the match head.
