One kilogram of ammonia initially at 8.0 bar and 50°c undergoes a process to 4.5 bar, 20°c while being rapidly expanded in a piston–cylinder assembly. heat transfer between the ammonia and its surroundings occurs at an average temperature of 40°c. the work done by the ammonia is 40 kj. kinetic and potential energy effects can be ignored. determine the heat transfer, in kj, and the entropy production, in kj/k.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
