what is the amount of pressure exerted by a book that weights 12N onto a desk if it is laid on its longest side and has dimensiona of 0.25m x 0.20m x 0.02m?

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.
