Arigid box containing one mole of air at temperature to (in k) is initially in thermal contact with an "infinite' heat-capacity reservoir" at the same temperat ure to. the box is removed from the reservoir and a cyclic engine is used to take some heat from the reservoir and put some into the air in the box. what is the minimum amount of work from to to ti? express w in terms of to, ti and the gas constant r, and state units. ignore vibrational degrees - of-freed om in the air molecules and the heat capacity of the container. would inclusion of vibrational degrees- of- freedom increase or reduce the value of w?
