Heat is a thermal energy that flows from the cooler areas to the warmer areas. 2. An object is either good conductor of heat or a poor conductor of heat. 3. Liquids conduct heat better than solids and gases. 4. Metals are good conductors of heat. Materials that do not allow electricity to flow through are are called conductors 6 Thermal conductivity is a property of materials that allows heat to pass through them easily. 7. Materials that allow electricity to flow through are called conductors. 8. Electricity can be dangerous. 9.
