Color physical or chemical
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. We can observe some physical properties, such as density and color, without changing the physical ...The reason why you love your dog. Dog owners already know in their bones that they and their pets love one another. Now, a new study has confirmed it, finding that love is chemical...Leaves yellow as the result of a biochemical process, meaning it is a chemical reaction that occurs in a living thing. Even though some people think the change in the color of tree leaves in fall is an example of a physical change, the color change actually occurs because of chemical changes inside the leaf.

We would like to show you a description here but the site won’t allow us.Physical properties 1. Color 2. Density 3. Boiling point (molecular make up of molecules doesn't change) Physical properties are any properties of matter that can be measured or observed without changing or altering the chemical identity of matter. Physical properties are used to describe matter. Color, texture, density, boiling point, melting point, freezing …Chemical: The dark grey nail changes color to form an orange flaky substance (the rust); this must be a chemical change. Color changes indicate chemical change. The following reaction occurs: \(\ce{Fe} + \ce{O_2} \rightarrow \ce{Fe_2O_3}\) Physical: because none of the properties changed, this is a physical change.
Chemical: The dark grey nail changes color to form an orange flaky substance (the rust); this must be a chemical change. Color changes indicate chemical change. Physical: Because none of the properties changed, this is a physical change. The salt is easily retrieved by evaporating or boiling off the water.Color changes indicate chemical change. The following reaction occurs: Fe +O2 → Fe2O3 Fe + O 2 → Fe 2 O 3. Physical: because none of the properties changed, this is a physical change. The green mixture is still green and the colorless solution is still colorless.

These dyes are based on an observation made over 150 years ago, that a chemical called paraphenylenediamine (PPD) produces brown shades when exposed to oxidising agents. Today, PPD is still one of the primary chemicals used in hair dyes as a primary ...Chemicals that touch skin can lead to a reaction on the skin, throughout the body, or both.

A chemical change occurs when substances combine (the reactants) to form new substances (the products) as atoms are rearranged. Common evidences of a chemical change include a change of color, odor, temperature, the formation of a gas, or a precipitate A physical change occurs when there is a change in physical properties of …Yes! Yes, blue color is a physical property of an object. A physical property is a characteristic of a substance that can be observed or measured without changing its chemical composition. Blue color is one such property, as it can be observed and identified without causing any chemical change to the object itself.
