Which best explains why a wooden spoon can be used to stir hot soup on the stove?

• Wood is a good conductor of heat and transfers energy to the spoon.

• Wood is a poor conductor of heat and transfers energy to the spoon.

• Wood is a good conductor of heat and does not allow the transfer of energy to the spoon.

• Wood is a poor conductor of heat and does not allow the transfer of energy to the spoon.

What is the definition of CONDUCTION?

• When heat is transferred from objects like rays of light or electromagnetically.
• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.
• When heat transfers from objects that are touching.
• When heat transfers through the heater or AC in your house.
