Which of the following statements is INCORRECT regarding metals? 

Correct option is C

The correct answer is: C) Lead and mercury are comparatively good conductors of heat

Explanation:

• Lead and mercury are poor conductors of heat compared to most other metals.
• Metals like copper, silver, and aluminium are excellent conductors of heat.
• Other statements are correct: metals are malleable and ductile (can be drawn into wires) and have a shiny surface when pure.

Information Booster:

• Good thermal conductivity is a key property of most metals.
• Ductility allows metals to be drawn into thin wires for electrical and mechanical uses.
• Lustre (shiny appearance) is a typical characteristic of metals in their pure state.

Additional Knowledge:

• Lead is dense and soft, used in batteries and radiation shielding.
• Mercury is liquid at room temperature, making it unsuitable for heat conduction purposes.
• Silver and copper are the best thermal conductors among metals.
