Term
|
Definition
The rate of cooling of an object-whether by conduction, convection, or
radiation-is approximately proportional to the temperature difference ~ T
between the object and its surroundings. |

|
Term
|
Definition
| motion that carries the molecule from one place to another |
|
|
Term
|
Definition
| In addition to the translational kinetic energy of jostling molecules in a substance, there is energy in other forms. There is rotational kinetic energy of molecules and kinetic energy due to internal movements of atoms within molecules. There is also potential energy due to the forces between molecules. So a substance does not contain heat-it contains internal energy. |
