I think it's down to the process of trapping air: like the hairs on our bodies. The fine hairs on the feather trap warm air and insulate the bird. The downy feathers (closer to the bird's skin) are the real air trappers and are not waterproof. The alignment, or lie, of the feathers is important, too.
the scientific name is Florometra serratissima
Insulation is keeping the hot material hot and vice versa. There is no one best insulator but many. Blanket is one example of a good insulator that keeps you warm.Metals like sodium (Na) are the best conductors.Silicon (Si) is a semiconductor---somewhere in between a metal and a non-metal.Carbon (C) is a non-metal, and in theory would be considered an insulator as most nonmetals are. However, graphite can conduct electricity and so can carbon nanotubes. These are exceptions to the general rule that nonmetals are insulators because of their special structures.So C should be your answer, but it is an iffy question to begin with. Easier if the non-metal was something like sulfur.this is he correct answerSi.
The scientific name for a chicken feather is "plumage." Feathers are composed of beta-keratin, a protein that gives them strength and flexibility. Feathers serve various functions for chickens, such as insulation, waterproofing, and communication.
Friction involves two substances rubbing against each other. As this happens, one substance may lose electrons, thus becoming positively charged. Consequently, the other substance gains these electrons, becoming negatively charged.
switch...this break the flow of electricity, from a circuit
Yes
Concrete is one of the worst insulators
insulator
it depends what type of insulator youre talking about. wood is a good thermal insulator and rubber is a good electrical insulator A perfect vacuum is the best insulator.
Yes it is a good insulator
Rubber is an object that is a good insulator.
its a good insulator and a good insulato
insulator. it is not a very good insulator though.
insulator. it is not a very good insulator though.
is foam dirt an metal a good insulator
What is a good insulator for a igloo project
insulator. it is not a very good insulator though.
