Step 1
:

Understand the problem and identify the heat transfer modes involved. In this case, a spoon is sitting in a bowl of soup, and we want to determine how the spoon gets warmer. The heat transfer modes involved are conduction and convection.

Step 2
:

Explain the concept of conduction. Conduction is the process of heat transfer through a solid material due to the collision of microscopic particles. In this scenario, the heat from the soup (a hot liquid) is transferred to the spoon (a solid material) through conduction.

Final Answer

The spoon gets warmer after sitting in a bowl of soup primarily due to conduction, the process of heat transfer through a solid material. Convection, the process of heat transfer in a fluid, plays a minor role in this scenario, and radiation's contribution is negligible.
