Quiz#4 AME230 Monday Feb. 18 2008 N a m e : Two kilograms of Refrigerant 134a, initially at 2 bar and occupying a volume of 0.12 m 3 , undergoes a process at constant pressure until the volume has doubled. Kinetic and potential energy effects are negligible. Determine the work and heat transfer for the process, each in kJ. Sketch the system and define boundaries. Show all energy changes and interactions on the sketch. Define properties that fix State 1 Define properties that fix State 2 Sketch three isotherms on a P-v diagram, clearly indicating which isotherms are the higher temperatures Show States 1 & 2 on a P-v diagram
