Considering the available options, the statement about thermal radiation that is always true is: " A hot object emits more total radiation per unit surface area than a cool object."

  • This is because hot objects have atoms that move quickly.

  • These fast-moving atoms affect and disturb electrons, thereby generating more radiation through the emission.

  • Generally, the radiation emitted from a hot object is referred to as Blackbody radiation.

Hence, in this case, the correct answer is option D. "A hot object emits more total radiation per unit surface area than a cool object."
