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.

What os the equation of the line described below written in slope-intercept form? the line passing through point (0,0) and parallel to the line whose equation is 3x+2y-6=0

What is the state of matter with a specific volume but no definite shape
