Answer 2

A steel spoon will be hotter than a wooden cylinder when left in the sun for an hour.

Explanation:

Wooden cylinder:

• Wood is a poor conductor of heat (as well as other forms of energy) as it is covalently bound as a compound.
• It does not have any free electrons that scatter around to conduct different forms of energy.

Steel spoon:

• Since metals have more electrons than wood they can conduct heat much better than wood.
• Heat causes molecules to vibrate. As they vibrate, they collide with their neighbor molecules, transmitting the energy of their motion.
• When one group of molecules sets another to vibrate, heat conduction takes place.
