Which of the following determine the kind (wavelength) and amount of radiation that an object emits?

The correct answer is A. Temperature.

The amount and type of radiation emitted by an object depends on its temperature. The hotter an object is, the more radiation it emits, and the shorter the wavelength of that radiation. This is why objects that are very hot, such as the sun, emit visible light, while objects that are cooler, such as a campfire, emit infrared radiation.

Thermal conductivity is a measure of how easily heat can flow through a material. Density is a measure of how much mass is contained in a given volume. Latent heat is the heat that is absorbed or
