6.Conduction

7.Convection

8.Convection

9.Conduction

Explanation:

6.Conduction. Vacuum is a poor heat conductor and will thus prevent heat transfer to the surrounding environs.

7.Convection. Heat reaches your body by way of convection. Hot air is forced from the fire sources and is in effect transfered around the room.

8.Convection. This form of convection is known as forced convection. Cool air is forced through fluid currents around the room.

9.Conduction. Conduction is enhanced by the temperature difference between objects and their thermal conductivity. The metal pole has a higher thermal conductivity than the tongue. The tongue will in effect transfer its heat to the metal pole thus its freezing.
