The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step 1: Understand the Assertion The assertion states that "In the human body, the heart acts as a pump that circulates blood through different parts of the body, transferring heat by forced convection." - **Explanation**: The heart indeed functions as a pump, circulating blood throughout the body. Blood carries heat, and as it moves, it can transfer heat to surrounding tissues. This process is similar to forced convection, where a fluid (in this case, blood) moves and transfers heat. ### Step 2: Understand the Reason The reason states that "In forced convection, material is forced to move by a pump or by some other physical means." - **Explanation**: Forced convection occurs when a fluid is moved by an external force, such as a pump or fan. In the case of the human body, the heart serves as the pump that forces blood to flow, thus facilitating heat transfer. ### Step 3: Analyze the Relationship Now we need to determine if the reason correctly explains the assertion. - The assertion is correct because the heart does pump blood, and this process involves heat transfer. - The reason is also correct as it accurately describes forced convection and how it applies to the heart's function. ### Conclusion Both the assertion and the reason are correct, and the reason provides a valid explanation for the assertion. ### Final Answer - Both the assertion and the reason are correct, and the reason is the correct explanation for the assertion. ---
