Question

3 A potter uses force to change the shape of wet clay. How is this useful?​

Answer 1

Answer:

These two actions lead to different kinds of changes.

1. When the lump of clay is shaped into a pot, only its physical properties are changed and chemically it remains clay.

2. When the pot is baked in the oven, its chemical properties are changed now we cannot get back the original clay using any physical process.
