The pistons of two identical cylinders are rigidly connected in such a way that the volumes under the pistons are equal to each other. At temperature T, air is introduced into the cylinders in such a way that the pressure in one of the cylinders is equal to P. Then this cylinder is heated to temperature T1. What pressure will be established in it? The temperature T is maintained in the second cylinder. The atmospheric pressure is equal to Po. Neglect the weight of the pistons.
