Five moles of nitrogen are expanded from an initial state of 3 bar and 88c to a final state of 1 bar and 88°c. you may consider n2 to behave as an ideal gas. answer the following questions for each of the following reversible processes: (a) the first process is isothermal expansion. (i) draw the path on a po diagram and label it path a. (ii) calculate the following: w. q。au_ah. (b) the second process is heating at constant pressure followed by cooling at constant volume. (i) draw the path on the same po diagram, label it path b (ii) calculate the following te, qauah

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
