Question

1. How does a blacksmith change iron into different tools? What type of change occur in iron?

Answer 1

Part 1: Blacksmith changes iron $\left(\mathrm{Fe}\right)$ into different tools

• The blacksmith first heats the iron and after some time it becomes red hot iron.
• Now, the hot iron is soft and blacksmith hammers this hot iron to make tools of different shapes.

Part 2: Change that occurs in iron

• The change that occurs in iron due to heating is a reversible change.
• By heating the tool, we can get initial iron from that.
