Expert Answer
(i) There will be no flow of heat either from iron ball to water or from water to iron ball since both water and iron ball are at same temperatures so heat transfer will not take place.
(ii) Heat flows from higher temperature to lower temperature. So heat will go from hotter end to colder end.
