A thermally insulated cylinder, closed at both ends, is fitted with a frictionless heat conducting piston which divides the cylinder into two parts. Initially, the piston is clamped in the center, with 1 litre of air at 200 K and 2 atm pressure on one side and 1 litre of air at 300 K and 1 atm on the other side. The piston is released and the system reaches equilibrium in pressure and temperature, with the piston at a new position. The final pressure is ..... atm (Assume air to be an ideal gas) upto two decimal places.
