Question

question 21 of 30
through what process is heat transferred between a hot pan and vegetables placed in the pan?

a. refraction

b. radiation

c. conduction

d. convection

Explanation:

• Option A: Refraction is the bending of light, not heat transfer, so A is incorrect.
• Option B: Radiation is heat transfer via electromagnetic waves (e.g., sun's heat), not direct contact, so B is incorrect.
• Option C: Conduction is heat transfer through direct contact (molecules colliding). A hot pan and vegetables in it are in direct contact, so heat transfers by conduction.
• Option D: Convection is heat transfer via fluid (liquid/gas) movement, not solid - solid contact here, so D is incorrect.

Answer:

C. Conduction
