They are polysterene foam and fiber glass (not encouraged due to irritation of the skin when broken).
A rubber band is an insulator. It does not conduct electricity and is used to prevent the flow of electric current.
Acrylic is not a good electrical insulator because it is a conductor of electricity. However, it can be a good thermal insulator as it has low thermal conductivity.
Iron is a conductor of electricity. It allows the flow of electric current due to its high number of free electrons that can move easily within the material.
A mirror is a conductor of light because it reflects and allows light to pass through easily. However, it is an insulator of electricity because it does not conduct electric currents.
Wool is a good insulator because it has natural crimped fibers that create small air pockets which trap heat. These air pockets act as barriers to prevent heat from escaping, making wool a good insulator that keeps you warm in cold conditions. Wool also has moisture-wicking properties, allowing it to regulate temperature and keep you comfortable in varying weather conditions.
aluminum foil is going to be the worst insulater, paper is a good insulater but not the best, so the best is cotton.
water remains warm when there is ice on it because ice is an insulater and it does not conduct heat due to which coldness cannot go through it.
No.
Its a insulater
No it is a conductor
a pencil eraser
Mica
insulater
it is a girl
conducter
we can keep water cool by kept it in a insulater and in a water cooler which have a special layer made by any insulater
the best insulater would probably be aluminum foil. the reason for this is that it reflects heat and light. That's how solar ovens work.
