an ideal gas (which is is a hypothetical gas that conforms to the laws governing gas behavior) confined to a container with a massless piston at the top. (figure 2) a massless wire is attached to the piston. when an external pressure of 2.00 atm is applied to the wire, the gas compresses from 4.40 to 2.20 l . when the external pressure is increased to 2.50 atm , the gas further compresses from 2.20 to 1.76 l . in a separate experiment with the same initial conditions, a pressure of 2.50 atm was applied to the ideal gas, decreasing its volume from 4.40 to 1.76 l in one step. if the final temperature was the same for both processes, what is the difference between q for the two-step process and q for the one-step pr4ocess in joules? express your answer with the appropriate units.
