A quantity of heat ΔH is transferred from a large heat reservoir at temperature T to another large heat reservoir at temperature T/2. The heat reservoir have such large capacities that there is no observable change in true temperature. The ratio of the entropy change of the entire system to the entropy change in heat reservoir at temperature T/2 is?
