Heat conductivity and radiation

Science tip:

Properties of heat conductivity, absorption of radiation as thermal energy, and heat capacity can be confusing.

Heat conductivity is the property of a material’s ability to conduct heat. The better the conductivity, the faster heat can transfer from one end to another.

The absorption of heat through radiation – sometimes less accurately called "heat absorption" – depends on the surface of the material. Whether it is black / white, matt or smooth.

Heat capacity – is the measure of how much heat a material can take or is required to increase its temperature by 1
