Physics

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 L . When theexternal pressure is increased to 2.50 atm, the gas furthercompresses from 3.20 to 2.56 L . In a separate experiment with thesame initial conditions, a pressure of 2.50 atm was applied to theideal gas, decreasing its volume from 6.40 to 2.56 L in one step.If the final temperature was the same for both processes, what isthe difference between q for the two-step process and q for theone-step process in joules?

Note that internal energy is a state function That means internal energy of the gas can be expressed as function of two state variables eg U fTV For an ideal gas internal function can be expressed of temperature alone But is not necessary to make See Answer
