Activity 3.4 Class 10 Science

In this activity, we will discuss the property of ductility of metals.

Aim of the activity

To identify ductile metals

Materials Required

    1. Iron

    2. Copper

    3. Aluminium

    4. Lead

Observation

The following metals are available in the form of wires:

    1.  Copper is used in electrical wiring

    2. Aluminium is used in power cables and wiring

    3. Iron is used in binding wires and construction

    4. Lead is not used for wires

Explanation

The ability of wires to be drawn into wires is known as ductility.

1. Copper and aluminium are highly ductile

2. Iron is comparatively less ductile

3. Lead is not ductile

Conclusion

This activity demonstrates the comparison of the ductility of different metals.
