Slide 4 - Tekstslide

Molecular Motion during conduction:

- During conduction the 
 molecules speed up and the 
faster-moving molecules 
slow down.

Slide 5 - Tekstslide

  - transfer of energy by the movement of heated particles.
- The movements are known as currents that move from warmer to cooler parts of the substance. 
- Occurs in liquids and gases.

Slide 6 - Tekstslide

Molecular Motion during Conduction: 
 - An increase in thermal energy causes the molecules move faster and spread further apart. This causes the density to decrease and the molecules to rise in the current.

- A decrease in thermal energy causes the 
molecules slow down and contract.
 This causes the density to increase and 
the molecules to sink in the current.

Slide 7 - Tekstslide

- transfer of energy through 
electromagnetic waves.
- Occurs fastest in gases.
- Can be absorbed or reflected.
- Can travel through space and between molecules.
