Correct answer: A. inside boiler furnaces
- A. inside boiler furnaces
- B. during melting of ice
- C. through the surface of the insulted pipe carrying steam
- D. from refrigerator coils to freezer of a refrigerator
Explanation
Inside a boiler furnace, heat reaches the surroundings by conduction through solids, convection through moving hot gases, and radiation from the flame and hot surfaces. The other situations do not normally involve all three mechanisms simultaneously in the stated form.
