Answer 2

The incorrect statement is O (d). The poorest conductor of heat among the metals is gold and silver,

• Metals are considered good conductors of heat and electricity .
• Both gold and silver being metals are good conductors of heat .
• They have free electrons that are not bound to the atoms . Hence, they transfer heat easily .
• As gold and silver are heated free electrons close to the heat source are heated which makes them move faster and collide with other electrons . This makes them move even faster.
• Therefore, both gold and silver are good conductors of heat .
