They are a physical change because it is not like burning where a new substance is being formed.
I would think it to be a Physical Change. Not chemical.
Melting of ice with salt is example of physical change as there is no chemical reaction involved .
No, a decaying compost pile is not an example of a physical change. The process of composting results in a different physical appearance or state -- which is physical change -- but it is not reversible and necessitates a change in structure -- which is chemical change.
A physical change
No, a change of state is not a chemical change, for it can be changed back to its original form and their is no change in the molecular composition of the substance. A chemical change is when it cannot be changed back. The above example is an example of a physical change. Example:- ice when heated changes into water and water when cooled changes into ice.
A physical change is melting.A chemical change is combustion.
Boiling is a physical change, not chemical.
Vaporization is a physical change, not chemical.
Chemical change.

Boiling is a physical change.
Rusting is the oxidation of a metal and is an example of a chemical change.
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.
Physical change
Boiling water is physical change.
No it is an example of a physical change
Physical there still the same mixture but blended together not a totally different substance.
