This is a physical change.
No.
This darkening involve chemical reactions.
A chemical change occurs when substances show new properties. This involves a rearrangement of atoms leading to the formation of new chemical bonds, resulting in the creation of a new substance with different properties than the original substances.
A glass tube is physical. Its composition, structure, and properties can be changed without altering its chemical composition, unlike a chemical change which would involve a change in composition.
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
No.
This darkening involve chemical reactions.
A physical change does not involve a change in the chemical composition or nature of the substance. It only affects the physical properties, such as shape, size, or state of matter.
No, bending wires is a physical change, not a chemical change. Chemical changes involve the formation of new substances with different chemical properties, while bending wires only alters their shape and does not change their chemical composition.
Chemical change always results in the formation of new substances with different chemical properties than the original substances. This can involve the rearrangement of atoms and the breaking or formation of chemical bonds.
A chemical change involves a change in a substance's chemical properties (characteristics that describe how it interacts with other substances).A physical change involves a change in a substance's physical properties(characteristics that describe certain features one can see with their 5 senses).
A chemical change occurs when substances show new properties. This involves a rearrangement of atoms leading to the formation of new chemical bonds, resulting in the creation of a new substance with different properties than the original substances.
A chemical reaction (change) results in a change in chemical properties.
No, a flying fish does not undergo a chemical change simply by flying. Chemical changes involve the formation of new substances with different chemical properties, which is not the case when a flying fish flies out of water.
Hardness is a physical change. It does not involve a change in the chemical composition or structure of a substance, but rather a change in its physical properties such as strength or resistance to deformation.
the properties that change are physical and chemical properties!!! :)
