This is a lava lamp. When the light bulb heats the wax, the wax rises. When the wax cools, it falls. This cycle of rising/falling is an example of:

• Conduction.
• Convection.
• Radiation.

Warm air rises and the cool air sinks demonstrates this type of heat transfer. 

• conduction
• convection
• radiation
• Insolation

• The cold energy from your hand transferred to your friend's hand through conduction.
• The heat energy from your friend's hand transferred to your hand through conduction. 
• The cold energy from your hand transferred to your friend's hand through convection.
• The heat energy from your friend's hand transferred to your hand through convection.
