Term
Describe how heat moves through solids. |
|
Definition
When the solid gets hot, the particles begin to vibrate faster. These particles bump into the slower moving particles. Soon all the particles are vibrating rapidly. Heat energy is passed along this way. |

Term
Describe how heat moves through liquids and gases. |
|
Definition
Heat energy moves through a liquid or gas through convection. The particles move from one place to another. At first only the air near the heat is heated. As this air is heated, the particles that make up the air begins to move faster and farther apart. Warm air rises (less dense) and the cool air moves down (more dense). The cool air pushes the warm air up. |
