Statement-1: There are two spheres made of same amount of material, one of them is hollow and other is solid. They are heated to same temperature and left in identical surroundigs. The initial rate of cooling will be greater for hollow sphere. Statement-2: The rate of heat loss depends on surface area and temperature.

both will expand equally

hollow sphere will expand more

solid sphere will expand more

the relative expansion of solid and hollow sphere depends on the material of sphere
