A \"Linde-machine\" is used to cool and liquefy air. The cyclicprocess uses three different states running
through three different processes, assuming air as a diatomic idealgas:
1 > 2: adiabatic compression with T1 = 23.0 °C, T2 = 150 °C, p1= 2.00 x 10^5 Pa and V1 = 2.50 dm^3
2 > 3: isobaric compression with T3 = T1
3 > 1: isothermal expansion
a) Draw the corresponding p(V) diagram of the cyclic process,numbering the different states and indicating
the direction of the individual processes (note that it is not aheat engine, but used to cool air).
b) What are the number of moles, the pressure at state 2 andvolumes at states 2 and 3?
c) What are the related work and heat taken up or released at eachprocess?
d) Calculate the total amount of work.
