WebAns: Convection: Transfer of heat by actual movement of molecules from hot place to a cold place is known as convection. Liquids and gases are poor conductors of heat. However, heat is transferred through fluids (liquids or gases) easily by another method called convection. WebSince the buoyant force from surrounding atmospheric air acts with the same force on both cold and hotter air molecules, the hotter, less dense air will tend to rise. Conversely, the cold air molecules will sink lower down.
