Apiston–cylinder device initially contains 0.07 m3 of nitrogen gas at 130 kpa and 180°c. the nitrogen is now expanded to a pressure of 80 kpa polytropically with a polytropic exponent whose value is equal to the specific heat ratio (called isentropic expansion). determine the final temperature and the boundary work done during this process.

Write a question about how changing temperature affects the gas inside the sports ball

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage
