Hot objects always cool down until they reach the same temperature as their surroundings. |
|
To what point do objects cool down to? |
|
|
|
Insulators reduce the speed (rate of) energy transfer. |
|
How do insulators work? |
|
|
|
A gas is a better insulator than a solid. |
|
What is a better insulator - air or plastic? |
|
|
|
A gas is a better insulator than a solid because gas particles are further apart than in a solid. Therefore the collision of particles are less frequent. |
|
Why is air a better insulator than plastic? class - what material makes the best insulator? |
|
|
|
Vacuums are the best insulators. |
|
What are the best insulators? |
|
|
|
Vacuums are the best insulators because there are no particles to collide in a vacuum. |
|
Why are vacuums the best insulators? |
|
|
|
Layers of clothes or fur, trap air so that the particles can not convect away, while the air still reduces conduction by reducing collisions. |
|
Why do humans wear clothes to keep warm? |
