Is grass an insulator?
Cellulose has the capacity to absorb moisture from the ambient air and release it, when the ambient air becomes drier. This characteristic has a balancing effect on the room climate, which is generally considered as one of the advantages of
renewable insulation
materials such as Grass Insulation.
Is pencil A conductor or insulator?
Conductor
. It a mixture of graphite and clay. It is a pretty good conductor. The harder the pencil lead like 6H – the worse a conductor/higher vresistance it will have.
What are 3 types of conductors?
Of all the materials, the top three are
silver, copper and aluminum
. Silver is known to be the best conductor of electricity but it is not widely used for economic reasons. It is only used for special equipment like satellites. Copper, though not as high as silver, also has high conductivity.
Which is a good example of a conductor?
Copper, steel, gold, aluminum, and brass
are also good conductors. In electrical and electronic systems, all conductors comprise solid metals molded into wires or etched onto circuit boards. Some liquids are good electrical conductors. Mercury is an excellent example.

Is air a conductor or insulator?
Air is
a good insulator
because it is a gaseous substance, therefore its spread-out molecular configure resists heat transfer to some degree.

Is cloth an insulator?
Cloth is a
good insulator
because it has no free electrons. Cloth is made up of covalently bonded atoms and thus it has no unbound electrons.
What are conductors give examples Class 6?
Conductors are objects that allow electricity to pass through them.

are good conductors of electricity.
What are conductors and insulators give examples Class 6?
Materials which allow electric current to pass through them are called conductors of electricity. Examples are
iron nail, key, safety pin, water, human bodyetc
. Materials which do not allow electric current to pass through them are called insulators of electricity. Examples are rubber, plastic, glass, air, clothetc.
What are insulators give two examples Class 6?
Example:

How many types of conductors are there?
There are
four types
of conductors, namely, good conductors, semiconductors, resistors and non-conductors. Non-conductors are also termed as insulators.
What materials are insulators?
