| Question | Answer |
|---|---|
| measure of the average kinetic energy of all the particles in an object | temperature |
| sum of the kinetic energy and potential energy of the particles in an object; is transferred by conduction, convection, and radiation | thermal energy |
| thermal energy that flows from a warmer material to a cooler material | heat |
| amount of thermal energy needed to raise the temperature of 1 kg of a material 1C | specific heat |
| transfer of thermal energy by collisions between particles in matter at a higher temperature and particles in matter at a lower temperature | conduction |
| transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from one place to another | convection |
| transfer of thermal energy by electromagnetic waves | radiation |
| material in which electrons are not able to move easily | insulator |
| device used in an active solar heating system that absorbs radiant energy from the Sun | solar collector |
| study of the relationship between thermal energy, heat, and work | thermodynamics |
| states that the increase in thermal energy of a system equals the work done on the system plus the heat added to the system | first law of thermodynamics |
| states that is impossible for heat to flow from a cool object to a warmer object unless work is done | second law of thermodynamics |
| device that converts thermal energy into work | heat engine |
| heat engine that burns fuel inside the engine in chambers or cylinders | internal combustion engine |
