Explanation:
When a nail is hammered into a wooden plank, the head of the nail becomes hot. This phenomenon can be explained by the conversion of kinetic energy into heat energy. Let's break it down further:
Conversion of Kinetic Energy into Heat Energy:
- When the nail is hammered into the wooden plank, it undergoes mechanical work.
- The person hammering exerts a force on the nail, causing it to move and gain kinetic energy.
- This kinetic energy is transferred to the molecules of the nail, resulting in an increase in their average kinetic energy.
- The increased kinetic energy of the molecules leads to an increase in their random motion, which we perceive as heat.
Reasons for Choosing Option B:
- Option A suggests the conversion of chemical energy into heat energy, which is not applicable in this scenario. There is no chemical reaction taking place when a nail is hammered into a wooden plank.
- Option C suggests the conversion of mechanical energy into heat energy, which is partially correct. However, it does not specify the type of mechanical energy involved, which is kinetic energy.
- Option B specifically mentions the conversion of kinetic energy into heat energy, which accurately describes the process occurring when a nail is hammered into a wooden plank.
Therefore, the correct answer is option B - conversion of kinetic energy into heat energy.
Summary:
When a nail is hammered into a wooden plank, the head of the nail becomes hot due to the conversion of kinetic energy into heat energy. The kinetic energy gained from the hammering is transferred to the molecules of the nail, increasing their average kinetic energy and resulting in the generation of heat.
