Question

you are carrying out an investigation on heat transfer. you are identifying the effects of heat transfer on hot dogs. you have cooked some of the hot dogs in a frying pan on a stove and others were roasted near a fire. how would you conduct the third investigation to demonstrate the final method of heat transfer? conduction - you could boil the hot dogs convection - you could microwave the hot dogs conduction - you could cook the hot dogs in the oven convection - you could cook the hot dogs in an air fryer

Explanation:

There are three main types of heat transfer: conduction, convection, and radiation. Frying in a pan is conduction (heat transfer through direct contact). Roasting near a fire is radiation (heat transfer through electromagnetic waves). An air - fryer uses convection (heat transfer through the movement of a fluid, in this case hot air). Boiling is also conduction but not the final method needed here. Microwaving is a form of radiation heating, not convection as stated in option B. Cooking in an oven can involve both radiation and convection, but an air - fryer is a more pure example of convection for this context.

Answer:

D. convection - you could cook the hot dogs in an air fryer
