Question

A baker uses oven mitts to open an oven, take a loaf of bread out, and place it on a plate. In 3–4 sentences, identify three examples of thermal energy transfer in the scenario.(4 points)

Answer 1

1) Convection: hot air inside the oven transfers thermal energy to the loaf as it bakes (and rushes out when the oven is opened).
2) Radiation: the hot heating elements and oven walls emit infrared radiation that warms the surface of the bread.
3) Conduction: when the baker places the hot loaf on a cooler plate, heat flows directly from the bread to the plate by conduction.
