Problem P. 4551. (September 2013)

P. 4551. There is a massless piston, which can move frictionlessly, in the middle of a 1-metre long, horizontal tube, closed at both of its ends. In the left chamber there is a sample of Oxygen gas, and in the right chamber there is Hydrogen gas at the same tempereture. The mass of the hydrogen is one-fourth of that of the Oxygen. Where is the equilibrium position of the piston?
