The ideal gas in the amount of 0.5 mol is in the vessel between two pistons, which are connected by a spring, the rigidity of which is equal to 2.483 kN / m. Pistons can move without friction along the axis of the vessel, behind the pistons vacuum. The spring length in the unstretched state is 1 m, the piston area is 831 cm ^ 2, the gas temperature is 300 K. Determine the gas pressure in the equilibrium position. The answer is expressed in kilopascals.
