5. Convection

6. Conduction

Explanation:

Conduction

- Is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules

Convection

- Is a transfer of heat related to the movement that occurs within a fluid due to the rising of hotter materials paired with the sinking of colder materials

Radiation

- Is energy that comes from a source and travels through space at the speed of light
