| Question | Answer |
|---|---|
| measure of the average kinetic energy of all the particles in an object | temperature |
| sum of the kinetic and potential energy of the particles in ab 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 tempature of 1kg of a meterial 1oc. | specific heat |
| transfer of thermal energy by collisions between particles in matter at a higher temperature an particles in matter at a lower tempreture. | 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 |
| devise that converts thermal energy into work. | heat engine |
| heat engine that burns fuel inside the engine in chambers or cylinders. | internal combustion engine |
