Radiators are devices used for heating spaces by transferring heat through convection. They work by circulating hot water or steam through pipes within the radiator unit. As the liquid or steam heats the radiator, the surrounding air is warmed, providing heat to the room through convection and radiation.
Chapter 10 of Class 11 Physics focuses on thermal properties of matter. It deals with concepts like temperature expansion and heat transfer. The chapter explores different types of expansion such as linear superficial and cubical expansion. It also covers heat conduction convection and radiation with practical applications in daily life and industrial uses.
