Solution

Metals:
Metal is an element that rapidly produces positive ions (cations) and possesses metallic bonding.
The majority of metals are malleable and ductile.
Because the atoms in metals form a matrix through which outside electrons may easily travel, metals are good conductors of electricity and heat.
That is why immersion rods for heating liquids are made up of metallic substances.
Because the immersion rod needs an electric supply to get heated and heat liquids.
Hence, Immersion rods for heating liquids are made up of metallic substances.
