Answer 1

Physical change :

physical change include changes in the size or shape of matter. Changes of state—for example, from solid to liquid or from liquid to gas—are also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting.

Chemical change:

A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding.

Answer 2

The physical changes are those changes in which the inner composition of the elements doesnot change.

• Like the following one will change but the inner element compositon will change
• Texture
• Temperature
• Shape
• But in the chemical change the inner composition of the element will change. Means that it will transform into some other component.
