Answer to Question #52508 in Physics for john

Question

1)a/ The pressure exerted on an ideal gas at 2.00 atm and 300 K is reduced suddenly to 1.00 atm while
heat is transferred to maintain the initial temperature of 300 K. Calculate the heat, the work, and the change in
internal energy for this process.
b/ Suppose the pressure change in question 1/ is carried out reversibly as well as isothermally. Calculate the heat,
the work, and the change in internal energy for this process and compare the answers to those in the irreversible
expansion in one step.
c/ Suppose the pressure change in question 1/ is carried out in the opposite direction (compression). Calculate the
heat, the work, and the change in internal energy for this process in both a reversible and irreversible way.
