When you jump on a trampoline, you have energy while you are moving up or down in your jumps. You have energy each time you pause for an instant before changing direction at the top or bottom of a jump. At the top a jump because of gravity, and at the bottom of a jump because of the stretchinness of the trampoline.

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
