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

Question

Quizplus · Accepted Answer

The temperature of an object is the most important factor in determining the type and amount of radiation it emits. The hotter an object is, the more energy it has, and the more radiation it can emit. This is described by the Stefan-Boltzmann law, which states that the power radiated is proportional to the fourth power of the temperature. Therefore, the higher an object's temperature, the more radiation it will emit and the higher the frequency of that radiation will be. Choices A, B, C, and D do not determine the type and amount of radiation an object emits to the same extent as temperature.
