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 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.
Is steel wool physical or chemical change?
When the steel wool burns, it is oxidized and thus this is a chemical change.
Is ripping your jeans chemical or physical change?
Physical - there are no chemicals involved
Is mashing a banana a chemical change or physical change?

What type of weathering is more rapid?
Chemical weathering is typically more rapid than physical weathering because chemical reactions can break down minerals and rocks more quickly than physical processes like abrasion or freezing and thawing. Factors like high temperatures, presence of water, and presence of acids can accelerate chemical weathering.
A diamond is the hardest natural substance is this a physical or chemical property?
The hardness of a diamond is a physical property because it pertains to the material's ability to withstand scratching and abrasion. It is determined by the structural arrangement of its atoms and the strength of its covalent bonds.
Is polishing a physical change?
Yes, polishing is a physical change because it changes only the appearance of the material by smoothing its surface through abrasion, without altering its chemical composition.

Is blue color a chemical property or physical property?
Blue color is a physical property. It is a physical property because being blue does not change the chemical composition.
Is Melting does that changes as a physical or chemical?
It is a physical change because the chemical composition of the substance does not change.
Is Bread Rising Chemical or physical?
i believe it is chemical because it cannot be returned to its original state.
When table salt forms from its elements is it chemical or physical change?
