The primary factor which determines what type and how much radiation an object emits is its:
A) conductivity.
B) size.
C) color.
D) temperature.
E) density.

Question

Quizplus · Accepted Answer

The temperature of an object is the primary factor that determines what type and how much radiation it emits. This is based on the object's thermal energy and how much energy it radiates as electromagnetic waves. The hotter the object, the more radiation it emits and the higher the frequency of the radiation. Color, conductivity, size, and density can affect how an object absorbs or reflects radiation, but they do not determine the type and amount of radiation it emits.
