Term
| How can you measure the average energy of motion of the matter in a glass of water? |
|
Definition
| by using a thermometer to measure the temperature |
|
|
Term
| --- --- is the energy of motion of particles. |

|
|
Term
| How is thermal energy trasferred through conduction? |
|
Definition
| one piece of matter has to touch another piece of matter. |
|
|
Term
| --- is a measure of the average energy of motion of the particles in matter. |
|
Definition
|
|
Term
| Air temperature rises when the particles in the air move ---. |
|
Definition
|
|
Term
| If you measured the average energy of motion of the matter in a glass of water and the average energy has increased. What can you infer has happened? |
|
Definition
| Thermal energy was added to the water and it warmed up. |
|
|
Term
| If you measure the average energy of motion of matter in the glass of water a thrid time and the average energy had decreased. What could you infer had happened? |
|
Definition
| Thermal energy was taken away fromt he water and it cooled off. |
|
|
Term
| Does the same aount of water take up the most space as ice, as liquid water, or as water vapor? Why? |
|
Definition
| The same amount of water takes up the most space as water vapor. Water patricles move fastest when they are in the form of vapor, so there is more space around them. |
|
|
Term
| Would an all-metal barn be as warm in the winter and as cool in the summer as an all-wood barn? Why or why not? |
|
Definition
| A barn made of metal wold not be as warm in the winter or as cool in the summer as one made from wood. Metal is a good conductor, so the metal barn would conduct more heat from the inside to the outside in the winter and from the outside to the inside in the summer than the wood barn. |
|
|
Term
| What type of clothing should you wear to stay warm in cold temperature? How does it help? |
|
Definition
| Closthes that are good insulators are best to wear in the winter. They work by blocking the amount of heat that escapes from your clothing. |
|
