Chemistry

An ideal gas (which is is a hypothetical gas that conforms tothe laws governing gas behavior) confined to a container with amassless piston at the top. (Figure 2) A massless wire is attachedto the piston. When an external pressure of 2.00 atm is applied tothe wire, the gas compresses from 6.40 to 3.20 LL . When theexternal pressure is increased to 2.50 atmatm, the gas furthercompresses from 3.20 to 2.56 LL .

In a separate experiment with the same initial conditions, apressure of 2.50 atm was applied to the ideal gas, decreasing itsvolume from 6.40 to 2.56 LL in one step.

If the final temperature was the same for both processes, whatis the difference between q for the two-step process and q for theone-step process in joules?

Express your answer with the appropriate units.
