The assignment: a fixed quantity of an ideal gas (r 0.28 kj/kgk; cv-0.71kj/kgk) is expanded from an initial condition of 35 bar, 500°c, 0.1m, to a final state of1.3mand 20c using a reversible polytropic process. calculate: (i) the index of expansion; (ii) the change in internal energy; (ii)the amount of heat transferred to or from the gas. show all your working clearly-and legibly if you're handwriting your submission.
