Question

distinguishing between insulators and conductors
determine if each object is an insulator or a conductor.
radiator
winter coat
ice chest
frying pan
over mat
ceramic baking dish

Explanation:

• A conductor allows heat or electricity to pass through it easily. Radiators (usually made of metal like steel or aluminum) and frying pans (often made of metals like iron, aluminum) are good conductors of heat.
• An insulator resists the flow of heat or electricity. A winter coat (traps air, which is a poor heat conductor), ice chest (materials like plastic or foam that are insulators to keep cold in), oven mitt (materials like cloth, rubber which are heat insulators), ceramic baking dish (ceramic is a heat insulator) are insulators.

Answer:

• Conductor: radiator, frying pan
• Insulator: winter coat, ice chest, oven mitt, ceramic baking dish
