Question

22. (a) Explain the meaning of malleable and ductile.
(b) Why is sodium kept immersed in water.​

Answer 1

Answer:

• A malleable material is one in which a thin sheet can be easily formed by hammering or rolling. ... In contrast, ductility is the ability of a solid material to deform under tensile stress. Practically, a ductile material is a material that can easily be stretched into a wire when pulled as shown in the figure below.
• Sodium is a highly reactive metal. It react vigorously when exposed to air and water and therefore it is kept immersed in kerosene
