Apiston–cylinder device initially contains 0.07 m^3 of nitrogen gas at 130 kpa and 120 degree c. the nitrogen is now expanded polytropically (pvn=c) to a state of 100 kpa and 100 degree c. find the value of ‘n’ (in pvn=c) and determine the boundary work done during this process.

Asap and show ! a 14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
