In conduction process, the molecules of the solid pass the heat from one to another

Options

A. without themselves moving from their positions.
B. themselves move from one place to another
C. without themselves moving from one place to another
D. none of these

Explanation

**Step-by-Step Solution:**

1. **Understanding Conduction**: Conduction is a process of heat transfer that occurs in solids. It involves the transfer of thermal energy through the vibration and interaction of molecules within the material.

2. **Molecular Interaction**: In conduction, the molecules of the solid do not move from their fixed positions. Instead, they vibrate and collide with neighboring molecules. This collision transfers kinetic energy, which is perceived as heat.

3. **Heat Transfer Mechanism**: As one molecule gains energy (due to heat), it vibrates more vigorously and collides with adjacent molecules. This process continues, allowing the heat to move through the solid without the actual movement of the molecules themselves.

4. **Conclusion**: Therefore, in the conduction process, heat is transferred from one molecule to another without the molecules themselves moving from their positions. This confirms that the correct understanding of conduction is that it occurs without the displacement of molecules.

**Final Answer**: In conduction, the molecules of the solid pass the heat from one to another without themselves moving from their positions.
