Heat transfer by convection involves the movement of fluids, such as liquids or gases. The process is driven by ___ difference.

When we place ice cubes into a glass of water, the ice eventually melts because of thermal energy transfer. But in what direction does the heat transfer? Is it from the ice to the water or from the water to the ice? Draw arrows on the image to show the direction that the heat would flow.
