Q1 Difference between convection radiation

Answer 1

Both convection and radiation are two methods of energy tranfer through a medium.In convection the energy is transfered by the movement of the medium (eg:boiling water ,the hot water at the bottom of the pan rises up and cooler water moves down to replace it , causing a circular motion).radiation is the tranfer of energy itself.(eg: we feel hot when we go near a hot body or fire)
