Question

question 16 of 25 which scenario is an example of the transfer of thermal energy by radiation? a. a piece of chocolate melts in a persons hand. b. a microwave oven causes water molecules in a cup to vibrate faster c. a persons body temperature falls as the person swims in the ocean. d. a hot - water heating system warms a room

Explanation:

Thermal energy transfer by radiation involves electromagnetic waves. In a microwave oven, microwaves (a form of electromagnetic radiation) cause water molecules to vibrate faster, heating the substance. Option A is conduction (heat transfer through direct contact), option C is mainly convection (heat transfer through fluid movement), and option D is also related to convection and conduction in the heating - system process.

Answer:

B. A microwave oven causes water molecules in a cup to vibrate faster
