Explain how thermal energy is transferred by conduction.
List three materials that are good conductors and two that are a good insulator.
Answers
Answer:
Metal is a good conduction of heat. Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. These molecules then bump into nearby particles and transfer some of their energy to them. ... Thermal energy is transferred from hot places to cold places by convection.
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.
