Heat Transfer A hollow sphere and a solid sphere of the same material and equal radii are heated to the same temperature. In this case, Both the spheres will emit equal amount of radiation per unit time in the beginning Both B & C Both will absorb equal amount of radiation from the surrounding in the beginning The cooling rate will be the same for the two spheres and hence the two spheres will have equal temperatures at any instant Both the spheres will emit equal amount of radiation per unit time in the beginning Both B & C Both will absorb equal amount of radiation from the surrounding in the beginning The cooling rate will be the same for the two spheres and hence the two spheres will have equal temperatures at any instant ANSWER DOWNLOAD EXAMIANS APP
