Apiston-cylinder device contains 0.02 m3 of hydrogen at 300 k. it has a diameter of 10 cm. the piston (assumed weightless) is pulled by a connecting rod perpendicular to the piston surface. if the outside conditions are 100 kpa and 300 k, (a) determine the pull force necessary in kn to create a pressure of 50 kpa inside. (b) the piston is now released; as it oscillates back and forth and finally comes to equilibrium, the temperature inside is measured as 600 k (reasons unknown). what is the pressure of hydrogen at equilibrium
