Question

Why does the color come both in chemical and physical change?

Answer 1

Hey mate....

It's becuz....if it's chemical reaction it will change the colour of the chemical used will change......and also in the physical change....

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......

Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but can not usually be used to separate compounds into chemical elements or simpler compounds......

so that it comes in both..
