water forming water vapor is physical change
Blue color is a physical property. It is a physical property because being blue does not change the chemical composition.
It is a chemical property.
Polymerization is not a property; it is a type of chemical reaction.
Reactivity is a chemical property (in chemistry !).

Solubility in water is considered a physical property, as it involves how a substance interacts with water molecules physically to form a solution without any chemical reactions taking place.
it is a chemical property because it changes the chemical structure of the molecules in the base
chemical...main word reacts!
physical. because you can easily change it back to water form and/or a gas.
If something reacts with water to form a gas, it's demonstrating a chemical property. The reaction has caused it to become something new, which is a telltale sign of a chemical property.
Chemical property: Reacts with acid to form a salt and water through a neutralization reaction. Physical property: Acid-base indicators change color in the presence of an acid.
Its A physical change. When you boil water under a stove, The water evaporates and the chemical stays in the..pan or whatever you put in it.
