The air in an insulated, rigid compressed-air tank whose volume is 0.5 m3 is initially at 2240 kPa and 20°C. Enough air is now released from the tank to reduce the pressure to 2000 kPa. Following this release, what is the temperature of the remaining air in the tank? The gas constant of air is 0.287 kPa·m3/kg·K. The specific heats of air at room temperature are cp = 1.005 kJ/kg·K and cv = 0.718 kJ/kg·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
