a cube and a sphere of equal masses are kept at 373K. When cooled which body will first attain the temperature of 273K

Rama as the volume is same, the cooling off will depend on surface area. The thermodynamics of cooling will be affected by the surface-to-volume ratio. now as the vol is equal, , going by the relation between Sphere (Diameter=D) and Cube ( Side a) , D= 1.382a . So the Surface Area of Sphere is m

Hi rama can you elobarate your question
