A fuel/air mixture is placed in a cylinder fitted with a piston. The original volume is 0.122 L. When the mixture is ignited, gases are produced and 416 J of energy is released. Determine the new volume of the mixture if the constant is kept constant at 635 mmHg and all the energy released is converted to work to push the piston.
