A diatomic gas describes a Carnot cycle in which, through an isothermal expansion process at 850 K it passes from a pressure of 10 atm and a volume of 2 L at a pressure of 8 atm. Subsequently there is an adiabatic expansion and isothermal compression at a temperature of 310 K. Finally, in the adiabatic compression the initial point is reached at 10 atm of pressure and a volume of 2 L. Make a scheme of the process and...

A gass undergoes adiabatic expansion to a pressure of 760 Pa and a volume of 7.5 m3 . The gas then undergoes isothermal compression to a volume of 4m3 . The gas then undergoes an isochoric process and returns to 1800 Pa of pressure. (Find Q,W, delta U for this isochoric process.) a) Find Q b) Find W c) Find delta U

7.5) A 1.15 -mol quantity of monatomic ideal gas undergoes the
following cyclic process. The gas starts at point a at STP. It
expands isothermally to point b, where the volume is 2.2 times its
original volume. Next, heat is removed while keeping the volume
constant and reducing the pressure. Finally, the gas undergoes
adiabatic compression, returning to point a.

A three-step cycle is undergone reversibly by 3.90 mol of an ideal gas: (1) an adiabatic expansion that gives the gas 3.96 times its initial volume, (2) a constant-volume process, (3) an isothermal compression back to the initial state of the gas. We do not know whether the gas is monatomic or diatomic; if it is diatomic, we do not know whether the molecules are rotating or oscillating. What are the entropy changes for (a) the cycle, (b) process 1,...
