heat flows between two bodies due to difference in their

Options

A. Volume
B. Pressure
C. temperature
D. All of these

Answer

**Step-by-Step Solution:**

1. **Understanding Heat Flow**: Heat transfer occurs when there is a temperature difference between two bodies. The fundamental principle of thermodynamics states that heat flows from a hotter object to a cooler one.

2. **Identifying the Cause of Heat Flow**: The driving force for heat transfer is the temperature difference. When two bodies are in thermal contact, the body with a higher temperature will transfer heat to the body with a lower temperature until thermal equilibrium is reached.

3. **Conclusion**: Therefore, the correct answer to the question is that heat flows between two bodies due to the difference in their **temperature**.

**Final Answer**: Heat flows between two bodies due to the difference in their **temperature**.
