Question

Different Between Physical And Chemical Change.​

Answer 1

A new compound (product) results from a chemical change as the atoms rearrange themselves to form new chemical bonds. A chemical change always involves a chemical reaction. The starting materials and final product are chemically different from one another. Here are some examples of chemical changes:

Burning wood , Souring milk , Mixing acid and base , Digesting food , Cooking an egg.

No new chemical species forms in a physical change. Changing the state of a pure substance between solid, liquid, or gas phase is a physical changes since the identity of the matter does not change. A physical change involves changes in physical properties, but not chemical properties. For example, physical properties change during tempering steel, crystallization, and melting. Here are examples of physical changes:

Crumpling a sheet of aluminum foil , Melting an ice cube , Casting silver in a mold , Breaking a bottle , Boiling water
