Plastic, wood and paper are insulators and very poor conductors of electricity.
because the plastic is liter than the metal
The ak's gears are not metal, but they aren't plastic, they are a hard plastic better than abs.
Plastic is generally a better insulator than metal because it has higher electrical resistance and lower thermal conductivity. This property makes plastic a good choice for applications where electrical insulation or heat retention is needed. Metal, on the other hand, is a better conductor of heat and electricity.
Yes, metals are better conductors of heat than plastic.
it is a greater conducter of heat than styrofoam
Metal free weight tend to be heavier than plastic ones. It is always recommended to get real weights over plastic ones.
Metal spoons are better thermal conductors than plastic spoons. Metal materials, such as stainless steel or copper, are able to transfer heat more effectively than plastic materials, making metal spoons better suited for tasks that require heat conduction.
I understand that this is for the same reason that a metal transfers electricity better: this is a result of a large number of free electrons, that is, electrons that are relatively free to move around.
I would say that plastic cups are better for string telephones because you cant get string through a metal cup.
Wood resonates much better than plastic or metal.
A plastic cup holds more heat because plastic can't take out heat. Glass conducts heat away.
Yes, plastic can scratch metal surfaces because plastic is typically softer than metal.
