Question

    Which of the following is an example of heat transfer

    through convection?
    A Dry ice sublimating Correct Answer Incorrect Answer
    B Land and sea breeze Correct Answer Incorrect Answer
    C X-rays from an X-ray machine Correct Answer Incorrect Answer
    D Frying vegetables in a pan Correct Answer Incorrect Answer

    Solution

    Convection occurs through the bulk movement of molecules in fluids, such as air and water. Land and sea breezes result from this process. Other examples relate to different heat transfer mechanisms: conduction (frying vegetables), sublimation (dry ice), and radiation (X-rays).
