Sanding a block of wood is a physical change. This process involves the mechanical removal of material from the surface of the wood, altering its texture and appearance without changing its chemical composition. The wood remains wood, and its chemical properties are unaffected by the sanding.

Is sanding a table top a chemical change?
Nope... sanding a table top is a physical change
Is making a dress a nuclear change or chemical change?
Physical Change. =KDML= ;)
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
Is radium decaying to lead a chemical or physical change?
The decay of radium to lead is a nuclear change, not a chemical or physical change. It involves the transformation of radium atoms into lead atoms through the process of radioactive decay. This change is due to the emission of alpha particles and does not involve any chemical reactions or changes in the physical state of the substances.
Is changing the size and shapes of piece of wood would be a chemical change?
No, changing the size and shape of a piece of wood is not a chemical change; it is a physical change. In a physical change, the material's appearance or form is altered, but its chemical composition remains the same. For instance, cutting or sanding wood changes its dimensions but does not alter its chemical structure.
Is sanding a piece of wood physical changes or chemical change?

Is sanding rust off a bike a physical or chemical change?
Sanding rust off a bike is a physical change because it does not alter the chemical composition of the rust or the metal underneath. It only changes the physical appearance by removing the rust layer mechanically through abrasion.
Is sanding a table top a chemical change?
Nope... sanding a table top is a physical change
Is sanding wood is a physical or chmical change and why?
Sanding wood is a physical change because it does not alter the chemical composition of the wood. The process of sanding simply removes layers of wood through abrasion, changing its physical appearance and texture without changing its chemical structure. In contrast, a chemical change would involve a transformation at the molecular level, resulting in the formation of new substances with different chemical properties.
What type of change is sanding a piece of paper?
Sanding a piece of paper is a physical change because the paper's appearance and texture are altered, but its chemical composition remains the same.
Is splitting uranium in a power plant a physical nuclear or chemical change?
It is a nuclear change because there is a change in the nuclear structure of Uranium.

Is a phase change an example of a physical or chemical or nuclear or a covalent change?
A phase change is an example of a physical change, not a chemical, nuclear, or covalent change. During a phase change, the substance undergoes a change in state (solid, liquid, gas) without any change in its chemical composition.

Is a change that produces a new element a physical change?
No, it is a chemical change. ---------------------------------- Yes, it is a physical change because this change not involve a chemical reaction but a nuclear reaction followed by a change in the number of protons and neutrons.
