Explanation:
Since how I can't see the graph I'll explain as best as I can.
Friction is the process of two things rubbing against each other causing heat, and pressure. A example would be rubbing a stick into a log to start a fire.
Conduction is heat transfer that usually involves heat flowing from a hot object to a cold object increasing the cold objects temperature. A example would be putting a spoon in a pot of hot water and in result the spoon will also get hot.
Radiation is a type of transfer that involved the sun shining it's energy transforming it's light energy into electrical energy. Or increasing somethings temperature by using light.
Induction is the process of using a conductor to change the magnetic field of a magnet in order to do this you need a electrical conductor and a magnet you put the magnet in the conductor and the heat causes the magnetic field to change.
Hope this helps.
