a 3. When a system is taken from state a to state b in FIGURE 3 along the path ach, heat flows into the system is 40 J and 20 J of work is done by the system. Along the path adb, heat flows into the system is 36 J. d V FIGURE 3 a. Calculate the internal energy along the path ach? 12 Marks b. Calculate the work done by the system along path adb? 13 Marks c. If work done, W-13 for the return path of ba curve, calculate the quantity of heat, Q for this path? 13 Marks d. Take internal energy, Ex = 10 J. What is E.? 13 Marks e. Take Ex=22 J, how much heat for path ad and db? 15 Marks f. Using the First Law of Thermodynamics, explain why the molar heat capacity at constant pressure Cp is greater than the molar heat capacity at constant volume C for an ideal gas. 14 Marks
