The correct Answer is:
To solve the question "Which one of the following is the mode of heat transfer in which warm material is transported so as to displace a cooler material?", we need to analyze the different modes of heat transfer: conduction, convection, and radiation. ### Step-by-Step Solution: 1. **Understanding Heat Transfer Modes**: - **Conduction**: This is the transfer of heat through a material without the movement of the material itself. Heat is transferred from one particle to another through direct contact. - **Convection**: This involves the movement of warmer material (like a fluid or gas) which carries heat with it. As the warmer material rises, it displaces cooler material, allowing heat to be transferred. - **Radiation**: This is the transfer of heat in the form of electromagnetic waves. It does not require a medium and can occur in a vacuum. 2. **Identifying the Key Phrase**: - The question specifies "warm material is transported so as to displace a cooler material." This indicates a movement of material, which is characteristic of convection. 3. **Analyzing the Options**: - If the options include conduction, convection, and possibly a combination of both, we can eliminate conduction because it does not involve the movement of material. - Radiation can also be eliminated as it does not involve the transport of material. 4. **Conclusion**: - Since convection is the only mode of heat transfer that involves the movement of warmer material displacing cooler material, the correct answer is convection. ### Final Answer: The mode of heat transfer in which warm material is transported so as to displace a cooler material is **Convection**. ---
