| Question | Answer |
|---|---|
| Heat from the sun | Radiation |
| Absorption of electromagnetic waves of the sun | Radiation |
| Metal seat buckle becomes too hot to touch | Conduction |
| Water boiling | Convection |
| Is wood an insulator or conductor? | Insulator |
| Is metal an insulator or conductor? | Conductor |
| Cool air ________________, and warm air ___________________. | Sinks, rises (convection |
| How a stove heats | Conduction |
| How a microwave heats | Radation |
| Conduction | Heat energy is transferred when molecules within a substance collide. |
| Requires no medium for transfer | radiation (electromagnetic waves) |
| Convection | Heat is transferred because of density differences. |
| Conduction is the transfer of heat energy by ______________. | molecular contact (direct contact) |
| Radiation | Heat energy is transferred in waves. |
| Energy transferred through a fluid or gas where hot rises and cold sinks. | convection |
| Another name for heat energy | thermal energy |
| The amount of heat energy transferred depends on ___________________. | the difference in temperature between the objects. |
| Thermal energy moves from ______________ to ________________objects. | warmer, cooler |
| Occurs most easily in liquid and solids | conduction |
| Conductor | transfers thermal energy very well |
| Insulator | does not transfer thermal energy very well |
| Good conductors | silver, metal, gold, nickel, copper |
