| radiation | Energy that travels as electromagnetic waves, which include visible light, microwaves, and |
| heat | A fl ow of energy from an object at a warmer temperature to an object at a cooler |
| specific heat | The amount of energy required to raise the temperature of 1 gram of a substance by 1°C. |
| convection | The process that transfers energy by the motion of large numbers of particles in a |
| thermometer | A device that measures temperature through the regular variation of some physical |
| calorie | The amount of energy needed to raise the temperature of 1 gram of water by 1°C. |
| insulator | A material that does not transfer energy easily. |
| temperature | A measure of the average kinetic energy of all the particles in an object. |
| conduction | The process that moves energy from one object to another because they are touching |
| joule | The standard unit in which energy is measured. |
| conductor | A material that transfers energy easily. |
| degrees | Temperature is measured in these equally spaced units between two points. |
| kinetic theory of matter | States that all of the particles of matter are constantly in motion. |
| thermal energy | The total random kinetic energy of particles in an object. |
| One calorie | equal to 4.18 joules. |
