The cylinder, closed on both sides, is divided into two equal parts by a heat-proof piston. In both parts of the cylinder there are equal masses of gas at t0 = 27 ° C and pressure P0 = 760 mm Hg. Art. The length of the cylinder is L = 40 cm. At what distance dx from the middle of the cylinder will the piston move if the gas in one of the parts is heated to a temperature of t = 57 ° C? What pressure p will be established in each part of the cylinder (Fig.)?
