4. The amount of thermal energy needed to change a substance’s temperature by 1 degree Celsius.
When particles move more slowly, they have lower average energy. How does this affect temperature?
This makes the temperature lower

Conduction
Temperature scale in which 32 degrees is freezing
Farenheit
The forces holding liquid particles together are stronger than those holding gas particles together.
1. True
2. False
True
* The particles are stronger in liquids as they are closer together. Particles want to spread more in gases
What occurs during expansion?
1. Particles get more excited and move more with the addition of heat.
2. Particles lose energy and slow down.
3. Particles become denser.
4. Particles remain stationary.
1. Particles get more excited and move more with the addition of heat.
How does adding heat affect the volume of solids, liquids and gases?
Heat increases volume: particles move more when they're heated, causing them to move further apart and expand
