Question

which of these systems is an example of convection? water boiling in a pot food frying in a pan melting ice in your hand

Explanation:

Convection is the transfer of heat through the movement of fluids (liquids or gases). When water boils in a pot, the hot water (less dense) rises and the cooler water (more dense) sinks, creating a circular motion (convection current). Food frying in a pan is mainly conduction (heat transfer through direct contact between the pan and food). Melting ice in your hand is also conduction (heat transfer from your hand to the ice).
