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

Answer:

C. Conduction
