in which scenario is thermal energy being transferred by radiation?
Answer
Answer:
The scenario with the chicks under a heat - lamp (the third image).
Brief Explanations:
Thermal energy transfer by radiation occurs without a medium. A heat - lamp emits infrared radiation to warm the chicks, which is an example of radiation heat transfer. The first image shows convection in a lava lamp, the second image shows conduction (heat transfer through the cup to the hand), and the fourth image shows conduction (heat transfer from the iron to the cloth).
