Consider a piston-cylinder assembly in which air expands adiabatically from an initial state where pi= 100 lbf/in, u = 3.704 f/ib, and t = 1000°r, to a final state where p2 30 lb/in". the process is polytronic with n=1.4. the change in specific internal energy (in turib), can be expressed in terms of temperature change as au - (0.171)(12 - 11). determine the final temperature in "r). neglect kinetic and potential energy effects.

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
