Draw a picture that contains both heat transfer using Conduction, Convection and Radiation
Conductor: A material that allows heat to easily transfer through it. Examples include metal, water, and glass. Insulator: A material that does not allow heat to transfer through it easily. Examples include air, plastic, and wood. A mixture of both in different areas can help to regulate the rate of heat transfer.
The ability of a material to transfer heat is known as its thermal conductivity. Metals are good thermal conductors while plastics and wood are good thermal insulators. Some materials, known as superconductors, can transfer heat without any resistance. These materials can only be cooled to temperatures close to absolute zero. Certain materials, such as aerogels, can be used to trap air and create a thin layer of insulation. These aerogels can be used to make insulating clothing and even insulating paint.
