Answer 1

Answer:

A blacksmith beats a piece of hot iron to gives it the desired shape. Give reasons.

Answer 2

Required Answer:

☑A blacksmith first heats a piece of iron till it becomes red hot.

☑It then becomes soft and can be beaten into desired shape. 

☑Iron when heated and beaten it forms some shape and again heated it regain initial iron.

☑Thus, this change is a reversible change.
