Wood and organic matter undergoes a combustion reaction with oxygen to create new compounds, such as water, carbon dioxide, and other species.
A forest fire is a chemical reaction because it involves the combustion of organic matter producing heat, light, and various byproducts like carbon dioxide and water vapor. It is not a reversible reaction as the original substances are permanently transformed into new substances during the process.
Yes, the metal bar undergoing a color change due to heating in a fire is a physical change, not a chemical change. Chemical changes involve the formation of new substances with different chemical properties. Heating a metal bar until it glows red hot does not alter its chemical composition.
Yes, a forest fire is a chemical reaction that involves the rapid oxidation of fuel (trees, plants) in the presence of oxygen. This reaction releases heat and light energy, along with various byproducts such as smoke and ash.
Burning is a chemical change.
Burning is a chemical change.
A forest fire is a chemical change because it involves combustion, which is a rapid chemical reaction that produces heat and light. The burning of trees and vegetation in a forest fire involves the chemical reaction between the fuel (organic matter) and oxygen in the air to produce carbon dioxide, water vapor, and other byproducts.
Cooking is for example a chemical change.
Fire.
Yes, a forest fire is a chemical change because it involves the combustion of organic matter present in trees and plants, resulting in the release of heat, light, and various gases like carbon dioxide and water vapor.
A forest fire involves primarily a chemical change, as the combustion of organic materials (such as trees and plants) results in the release of heat, light, and gases. The transformation of these materials into ash and smoke is a chemical process.
A fire is a chemical change due to the irreversible changes that happen.
A forest fire is a chemical reaction because it involves the combustion of organic matter producing heat, light, and various byproducts like carbon dioxide and water vapor. It is not a reversible reaction as the original substances are permanently transformed into new substances during the process.
Yes, the metal bar undergoing a color change due to heating in a fire is a physical change, not a chemical change. Chemical changes involve the formation of new substances with different chemical properties. Heating a metal bar until it glows red hot does not alter its chemical composition.
Changes that take place within seconds are known as fast change. For example bursting of a fire cracker is a fast change and a forest fire can spread very fastly.
I would think it to be a Physical Change. Not chemical.
It is a chemical change.
A chemical change can not be reversed. Obviously the fire work can not be put back together because it has reacted, not being able to be reversed, and therefore, being classified as a chemical change.
