Convection currents are utilised in kettles and pans. The heating element is placed at the bottom, the hot particles near the heating element, loose mass, rise, they gain mass as they loose energy and fall back to the heating element.. :shallow_pan_of_food:
Conduction
Particles vibrate, collide nad transfer heat and as a result the heat is idssapated.
To stop conduction and to keep the house heated people use cavity wall which have gaps inside to stop the conduction.
