Problem
Two identical rooms in a perfectly insulated house are connected by an open doorway. The temperature in the two rooms are maintained at different values. The room which contains more air molecules is
(a) the one with the higher temperature;
(b) the one with the lower temperature;
(c) the one with the higher pressure;
(d) neither, since both have the same volume.
