In an industrial process, a fuel-air mixture is fitted with a piston. When the mixture is ignited at a constant pressure of 700mm Hg, 2.0 kJ of energy is released and is found to occupy a final volume of 200L. What would be the initial volume occupied by the mixture if all energy released is converted as work done by the system to push the piston?
