Is Colour change a physical or chemical property?
Color. The changing of color of a substance is not necessarily an indicator of a chemical change. For example, changing the color of a metal does not change its physical properties. However, in a chemical reaction, a color change is usually an indicator that a reaction is occurring.

What is a chemical property of steel?
Alloy Steel Alloy steels (like carbon steels) contain both carbon and iron, but add additional elements such as silicon, nickel, chromium, manganese, or vanadium. The extra elements added are what provide the additional features and varied chemical properties compared to carbon steels.
Why any chemical reaction is a chemical property?
A chemical property is any of a material’s properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance’s chemical identity. They can also be useful to identify an unknown substance or to separate or purify it from other substances.
Which type of property is ductility?
Ductility is the physical property of a material associated with the ability to be hammered thin or stretched into wire without breaking. A ductile substance can be drawn into a wire.
Is reactivity with vinegar a chemical property?
3.) Melting Point=Temperature at which a substance goes from solid to liquid. What are three examples of chemical properties? Reactivity with vinegar=Reacts with vinegar to produce new substances.
Is viscosity a chemical property?
Examples of chemical properties include reactivity, acidity, flammability, and more. So in short, viscosity is the resistance of a substance to flow and is a physical property because it describes the physical motion of the flow of a substance, how easily it flows.
What are the chemical properties of matter?
Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.
Is dissolving a physical or chemical property?
Relating Dissolution to Change Dissolving sugar in water is an example of a physical change. Here’s why: A chemical change produces new chemical products. In order for sugar in water to be a chemical change, something new would need to result. A chemical reaction would have to occur.
