state three uses of conductors and insulators ?
state three method of heat transfer and explain each method ?
Answers
Conductors conduct electrical current very easily because of their free electrons.
Insulators oppose electrical current and make poor conductors.
Some common conductors are copper, aluminum, gold, and silver.
Some common insulators are glass, air, plastic, rubber, and wood.
hope its helpful for you
please mark it as a brainliest
uses of conductor
it is used to carry current as the purpose of carrying current
used for making devices
used for making short circuit
insulator
it is used as protective cover against current
it is also used in devices manly to safe devices from external sock
it is also bad conductor of heat so used in pressure cooker as a handle .
three methods of heat transfer are
conduction = transfer of heat from one atom to another .(generally involve solid )
convection = transfer of heat from one molecule to another .(generally inbolve liquid)
Radiation = transfer of heat between two body between them there should be a gap having a medium like air ,or other gasses.
eg Sun
