Question

6. A potter working on his wheel, shaped a lump of clay into a pot. He then baked the pot in an oven. Do these two acts lead to the same kind of changes or different? Give your opinion and justify your answer.

Answer 1

• The making of pot by a lump of clay is a reversible change.
• The pot can be reversed back to the lump of clay.
• But after baking the pot in an oven, it cannot be reversed back to the clay.
• So, baking a pot is an irreversible change.
• Hence, these two acts by potter lead to different kind of changes where one is reversible and other is irreversible change.
