Electrical conductivity is not a change but is a physical property.
No, the process of ice melting at 0 degrees Celsius is a physical change, not a chemical property. It involves a phase change from a solid to a liquid state without any change in the chemical composition of the ice.
Scrubbing the floor is a physical change because the appearance or state of the floor is altered without changing the chemical composition of the materials involved.
It depends. In most cases, it is a chemical change as the different colored species have different chemical structures. However, it is possible to change color by very finely dividing particles of matter and this is a physical change.
It can be. Temperature increases usually induce physical changes in the broad sense. If the change in temperature merely induces a state change (for instance, the copper is melted - becoming a liquid) then it is purely a physical change. Presuming that heating will occur in the presence of air, it will also increase the rate of oxidation and, therefore, be indirectly inducing a chemical change.
Cutting a piece of copper in half is a physical change because it only alters the physical appearance of the copper without changing its chemical composition.
Electrical conductivity is not a change but is a physical property.
Copper metal conducting electricity is a physical property, not a physical or chemical change. Conductivity relates to how electrons move within a material, which does not alter the chemical composition of the copper itself.
chemical change
Yes
it can be both
This is a chemical change. Chemical reactions are chemical changes.
Electricity is not a physical or chemical change itself, but rather a form of energy that can result from both physical and chemical processes. When electrons flow through a conductor, it is a physical change, as the electrons are simply moving from one place to another. However, in some cases, electricity can also be produced through chemical reactions, such as in batteries, in which case it involves a chemical change.
The formation of rust on a car is a chemical change, not a physical change. It occurs when the metal reacts with oxygen and moisture in the air to form iron oxide. This process alters the chemical composition of the metal, making it different from its original state.
when water changes to water vapour by heating is an example of physical change. when water is divided into oxygen and hydrogen by passing electricity is an example of chemical change.
A physical change
It's neither since the copper isn't changing at all. Electrons are just flowing through the copper atoms.
Conductivity is a physical property because it pertains to the ability of a substance to conduct electricity or heat. It is related to the arrangement of particles in a material rather than its chemical composition.
