distinguish between molecules and atoms
Term | Defintion |
---|---|
Temperature | A measure of how hot or (or cold)something is; specifically, a measure of the average kinetic energy of the particles of an object |
Conduction | The transfer of heat by direct contact of particles |
Convection | The transfer of thermal energy by the circulation of movements of a liquid or a gas |
Radiation | The transfer of energy as electromagnetic waves |
Law of Conservation | the law that states that energy cannot be created or destroyed but can be changed from one form to another |
Energy | the capacity to work |
Work | the transfer of energy to an object by using a force that causes the object to move in the direction of the force |
Kinetic Energy | the energy of an object that is due to the object's motion |
Potential Energy | the energy that an object has because of the position, shape, or condition of the object |
Mechanical Energy | the amount of work an object can do because of the object's kinetic and potential energy |
Thermal Energy | the kinetic energy of a substance's atoms |
Heat | the energy transferred between objects that are at different tempatures |
Chemical Energy | the energy that is stored in chemical bonds |
Electrical Energy | the energy that results from the flow of moving charges |
Electromagnetic Energy | energy resulting from motion of the charged particles within atoms |
Sound Energy | energy given off by a vibrating object |
Nuclear Energy | the energy stored in the nucleus of an atom as a result of a strong nuclear forces |
Nuclear Fission | the splitting of the nucleus of a large atoms or more fragments; releases additional neutrons and energy |
Nuclear Fusion | the combination of the nuclei of small atoms to form a larger nucleus;releases energy |
