Answers
Answer:
Ans 1. Conduction
Ans 2.Of course the source of the heat is the stove burner. The metal pot that holds the water is heated by the stove burner. As the metal becomes hot, it begins to conduct heat to the water. The water at the boundary with the metal pan becomes hot.
The answer is conduction.
Ans 3. Convenction
Ans 4. convenction
Ans 5. When you sit by a campfire, most of the heat you are receiving from the fire does not come from hot air. It comes from thermal radiation. ... Since air is a good thermal insulator, conduction is the least effective way for heat to travel through air. Lastly, convection involves the bulk movement of pockets of heated fluid.
So, the correct answer is radiation.
Ans 6.Conventional ovens, which do not have fans, rely primarily on radiation from the oven walls, and to a lesser extent, on natural convection caused by temperature differences. The fans in convection ovens allow more heat to be transferred via convective heat transfer.
