A solid sphere and a hollow sphere of same material and size are heated to same temperature and allowed to cool in the same surroundings. If the temperature difference between each sphere and its surroundings is T, then:

the hollow sphere will cool at a faster rate for all values of T

the solid sphere will cool at a faster rate for all values of T

both spheres will cool at the same rate for all values of T

both spheres will cool at the same rate only for small values of T
