A sample of monatomic ideal gas occupies 5.00 L at atmospheric pressure and 300 K (point B in the figure). It is heated at constant volume to 3.00 atm (point B). Then it is allowed to expand isothermally to 1.00 atm (point C) and at last compressed isobarically to its original state. a.) Find Q, W and ∆U for each of the processes. b.) For the whole cycle find Q, W and ∆U. For monatomic gases, use Cv=3/2 R.

Problem 1 A 0.20 kg/s of air are compressed isothermally from P,= 100 kPa and V,= 0.15 m3/s to P,= 700 kPa. Determine: The work in kW and the change in entropy in kJ/s-K for (a) closed or non-flow process and (b) open or steady flow process with initial and final velocity of v, = 15 m/s and v, = 60 m/s, respectively.
part b please
Please help me with these questions a. What is the name given to this cycle, and why is it important? The volume of the ideal gas at point 1 is V1, etc. By analysing the adiabatic processes, we find that: V_2/V_1 = V_4/V_3 b. The work done during the isothermal processes is WC (between points 1 and 2) and WH (between points 3 and 4). Find an expression for the fraction WC / WH in terms of TC and TH. c. Apply the First Law of Thermodynamics to the isothermal processes to show that the efficiency of this cycle is (please see the image with the corresponding formula for question c) d. Use the Second Law of Thermodynamics to explain why no heat engine can be more efficient than a perfectly reversible engine. You may wish to include a heat flow diagram in your answer.
