Nitrogen (N2) gas within a piston-cylinder assembly undergoes a compression from P1 = 0.2 MPa, ?1 = 2.75 m3 to a state where P2 = 2 MPa. The relationship between pressure and volume during the process is P?1.35 = constant. For the N2, determine (a) the volume at state 2, in m3, and (b) the work in k

Wow that a lot of text for my tiny so i no wanna answer

Hope you find the answer

Answer earth,water,fire and air;

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
