Two sphere with radii in the ratio 1 : 2 have specific heats in the ratio x : y and densities in the ratio z : x . The ratio of their thermal capacities is

Two spheres made of same material have their radii in the ratio 1 : 3. They are heated lo the same temperature and kept in the same cool surroundings at a moderate temperature. Show that the ratio of their initial rates off all of temperature is 3 : 1 if the bodies are cooled by natural convection and radiation
