A 1.20 mol sample of an ideal monatomic gas,
originally at a pressure of 1.90 atm , undergoes a three-step
process: (1) it is expanded adiabatically from T1 = 573 K
to T2_2 = 373 K ; (2) it is compressed at
constant pressure until its temperature reaches T3; (3) it
then returns to its original pressure and temperature by a
constant-volume process.
Determine T3.
Calculate the change in internal energy for each process.
(E1,E2, & E3)
Calculate the work done by the gas for each process. (W1, W2,
& W3)
Calculate the heat added to the gas for each process. (Q1, Q2,
& Q3)
Calculate the change in internal energy, the work done by the
gas, and the heat added to the gas for the complete cycle. (Etotal,
Wtotal, & Qtotal)
