Question

question 14 of 20 which scenario is an example of the transfer of thermal energy by conduction? a. hot water heats up the cup that it is in. b. hot air circulates in an oven. c. you warm your feet in front of a fireplace. d. the air in a hot - air balloon is heated by a gas burner.

Explanation:

Conduction is the transfer of thermal energy through direct contact. In option A, hot water (a hot substance) is in direct contact with the cup, transferring heat to it. Option B is convection as hot air circulates (fluid - based heat transfer). Option C is radiation as heat is transferred from the fireplace to your feet without direct contact or fluid - based movement. Option D is also related to heating a fluid (air) by a heat source and involves convection.

Answer:

A. Hot water heats up the cup that it is in.
