An iron cube at a temperature of $$400$$ deg $$C$$ is dropped into an insulated bath containing $$10$$ $$kg$$ water at $${25^ \circ }C.$$ The water finally reaches a temperature of $${50^ \circ }C$$ at steady state. Given that the specific heat of water is equal to $$4186$$ $$J/kgK,$$ find the entropy changes for the iron cube and the water. Is the process irreversible ? If so, why?
