The statement that demonstrates radiation of heat is: **Mr. Smith keeps his baby chicks warm on a cold night by turning on an infrared heat lamp bulb in their coop.**
This is because infrared heat lamps emit infrared radiation, which transfers heat through the air without the need for direct contact or a medium like water or solid materials. The other options describe heat transfer methods that involve conduction (touching the lid) or convection (hot air balloon rising).
