Burning wood is a chemical change - although, like most chemical changes it is accompanied by a physical change. Usually we reserve the term physical changes for things like erosion, melting, or evaporation where no change in composition occurs.

Burning wood into ashes and smoke is a chemical change because it involves a chemical reaction between the wood and oxygen in the air, leading to the formation of new substances (ashes and smoke) with different properties from the original wood.

Is burning of wood and paper a chemical or physical change?

Burning of wood and paper is a chemical change because it involves a chemical reaction where the substances are transformed into new substances (ashes, carbon dioxide, etc.) with different properties than the original materials.

Is burning of branches physical change?

No, it's a chemical reaction with O2.In physical changes the chemical formula remains the same; like ice (H2O) and water (H2O). Burning wood is something like cellulose + O2 --> CO2 + H2O

Is ashes physical property or a chemical property?

Ash isn't a property of any sort. It is a form of matter containing a variety of substances each with its own set of physical and chemical properties.

Why the rusting of an iron pole is not physical change?

The rusting of an iron pole is a chemical change. An example of a chemical change would be crumbling a piece of paper. When you are crumbling this piece of paper, the contents of the paper have not change and you are able to uncrumble the paper there is no difference except the paper has wrinkles. :) However in an example of chemical change like a metal rusting, you cannot un-rust it, it was chemically changed. Another example of a chemical change would be burning a piece of paper to ashes.

Examples of chemical change?

Burning a paper. Any change where you can't go back to the original item is a chemical change. You can't go from ashes back to a paper. Crumpling a piece of paper is a physical change because it's still a piece of paper.

Is a log burning a chemical or physical change?

Chemical change, because it is irreversible. The chemical composition of the substance actually changes. A physical change is a change of state, like water to ice. There, H20 is still H20.

Is a tree burning to form ashes a physical or chemical change?

The process of a tree burning to form ashes is a chemical change. This is because the chemical composition of the tree is altered as it undergoes combustion, transforming into new substances such as carbon dioxide, water vapor, and ash.

Is Burning wood is an example of physical change.?

No, burning wood is an example of a chemical change because the bonds between the atoms in the wood are being broken and new substances are formed, such as ash and smoke. Physical changes, on the other hand, do not alter the chemical composition of a substance.

Is burning of wood and paper a chemical or physical change?

Is a tree burns to form ashes chemical change?

The parts of the tree that burn are undergoing a chemical change. The ashes remaining may or may not have undergone a chemical change, depending on the the chemical bonding that the atoms in the ash had before the tree was burned.

Is a chocolate changing from solid to liquid chemical change?

Of course not, it is not a chemical change. A chemical change includes the change in the molecular structure of something. For example, a burning paper turns into ashes after a while. This is a chemical change because you cannot return the ashes into paper again, hence, a change in its chemical structure happened. As another instance, a cube of ice melts into water--it is a physical change because you can always return it into an ice by freezing it, but don't expect it to have it in its original shape. A melting chocolate undergoes a physical change.

Is flammibilty a physical change?

Is boiling water for tea a chemical or physical change?

This is a physical change. Water can take on 3 forms, ice, gas, and liquid. These would be changes in state. Tearing, scratching, crushing, change in state, are all physical changes. Chemical changes must change the substance, not just the appearance. (i.e. Burning fire into ashes, fireworks exploding...)

What happens to matter when it undergoes a physical and chemical change?

During a physical change, the matter retains its chemical composition but its physical properties (such as shape, size, or state) may change. On the other hand, during a chemical change, the matter undergoes a chemical reaction, resulting in the formation of new substances with different chemical compositions.

Is wood turning into ash in a fire a physical change?

Yes, wood turning into ash in a fire is a chemical change because the chemical composition of the wood changes as it is burned. The wood undergoes a combustion reaction with oxygen to form new substances such as carbon dioxide and water vapor.
