Question

a pot of water is heated on an electric stove top and begins to boil. which transfers of thermal energy involved in this system are examples of conduction?
a. from the air above the pot as currents form
b. in the water as water currents develop
c. from the burner to the bottom of the pot
d. from the pot to the water

Explanation:

• Conduction is the transfer of thermal energy through direct contact between materials.
• Option A: Transfer from air above the pot as currents form is convection (heat transfer through fluid - air currents).
• Option B: Transfer in water as water currents develop is convection (heat transfer through fluid - water currents).
• Option C: Transfer from the burner to the bottom of the pot occurs through direct contact (conduction).
• Option D: Transfer from the pot to the water occurs through direct contact (conduction).

Answer:

C. From the burner to the bottom of the pot; D. From the pot to the water
