Answer:

  conduction

  convection

   radiation

Explanation:

       CONDUCTION:

                              Conduction occurs when two object at different TEMPERATURES are in contact with each other. Heat flows from the warmer to the cooler object until they are both at the same temperature.

                              example:A radiator is a good example of conduction.

         CONVECTION:                        

                                the MOVEMENT CAUSED within a fluid by the tendency of hotter and therefore less dense MATERIAL to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.  

                              example:ICE melting - Heat moves to the ice from the air.      

         RADIATION :  

                             radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium.

                                   example:ultraviolet light from the sun.
