A certain Carnot engine was built in a laboratory. The lab technicians found out that if the temperature of the cold reservoir is kept at 295 K, the efficiency of the engine is 26.0%. If the hot reservoir is kept at constant temperature, at what temperature must the cold reservoir be set, so that the efficiency of the engine is increased to 33.0%?
