BlakeWhite bodies are bad conductors of heat because they have air gaps and trapped air pockets within their structure, which limit the transfer of heat energy. White surfaces reflect more heat than they absorb, leading to lower heat conduction compared to darker surfaces. This is why white materials are used in insulation to reduce heat transfer.

Which materials are good or bad conductors of heat?
Good conductors of heat include metals like copper, aluminum, and silver, as well as materials like graphite and water. Materials like wood, plastic, and rubber are poor conductors of heat.
What are the differences between good and bad conductors of heat?
Good conductors of heat transfer heat easily and efficiently, such as metals like copper and aluminum. Bad conductors, known as insulators, resist the flow of heat and are poor at conducting it, such as materials like rubber, wood, and air. Conductors have high thermal conductivity, while insulators have low thermal conductivity.
Why is plastic foam fur and feathers bad conductors of heat?
Plastic foam, fur, and feathers are bad conductors of heat because they have a lot of air pockets trapped within them. Air is a poor conductor of heat, so materials that have a high amount of air trapped within them are also poor conductors of heat. This trapped air creates a barrier that prevents the easy flow of heat, helping to insulate the object or organism.
What are some good conductors and bad ones?
Good conductors of electricity include metals such as copper, aluminum, and silver due to their high availability of free electrons for easy movement of electrical charge. Insulators, like rubber and glass, are bad conductors because they have tightly bound electrons that do not move freely to conduct electricity. Semiconductors like silicon fall in between, as they can conduct electricity under certain conditions.
Why are liquids bad conductors of heat?
Liquids are bad conductors of heat because their molecules are not closely packed together like in solids, limiting the transfer of thermal energy between them. Additionally, the free movement of molecules in liquids also hinders the transfer of heat. This is why liquids take longer to heat up and cool down compared to solids.
