Question 11 (1 point) Listen A piston-cylinder device contains 3.9 kg of R-134a at 400 kPa and 50C. Now R- 134a goes through a process at constant pressure until its temperature drops to 11.5C. What is the magnitude of the work (in kJ) done during this process? (Do not assume ideal gas. Use property tables and linear interpolation instead.) Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point
