| Question | Answer |
|---|---|
| temperature | the particles in the object |
| thermal energy | the sum of the kinetic and potential energy in an object is the thermal energy of the object |
| heat | the thermal energy that flows from something at a hight temperature to something at a lower temperature. |
| specific heat | the amount of heat that is needed to raise the temperature. |
| conduction | the transfer of thermal energy by collisions between particles in matter. |
| convection | the transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from place to place. |
| radiation | the transfer of energy by electromagnetic waves. |
| insulator | a material in which heat flows slowly |
| solar collector | absorb radiant energy from the sun |
| thermodynamics | thermal energy,heat, and work are related. |
| first law of thermodynamics | the increase in thermal energy of a system equals the work done on the system plus the heat transferred to the system. |
| second law of thermodynamics | cool object to a warmer object unless work is done. |
| heat engine | a device that converts heat into work |
| internal combustion engine | fuel is burned inside the engine in chambers or cylinders. |
