Nitrogen (n2) gas within a piston–cylinder assembly undergoes a compression from p1 = 20 bar, v1 = 0.5 m3 to a state where v2 = 2.75 m3 . the relationship between pressure and volume during the process is pv1.35 = constant. for the n2 determine (a) the pressure at state 2, in bar, and (b) the work in kj.

Part a)

As we know that

here we know that

P1 = 20 bar

V1 = 0.5 m^3

V2 = 2.75 m^3

from above equation

so final state pressure will be 2 bar

Part b)

now in order to find the work done

explanation:

wheres the pic

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
