Both convection and conduction heat transfer need a medium (for example air particles, water, metal) through which to travel along with a temperature gradient within the medium. Radiation heat transfer does not need a medium through which to travel, it actually occurs most effectively in a perfect vacuum environment. Radiation is not just the heat from the sun, although the sun does in fact radiate heat. Everything around you is currently radiating heat as well (for example humans, computers, furniture, books, food, etc.)
convection conduction and radiation
conduction;convection,radiation.AND advection
convection conduction radiation
energy will always be transferred

INSULATION IS EEPING THE HEAT INSIDE AND convection and radiation I HAVE GOT NO IEA HOPE IT HELPS :))
