Actionand cu o forta F1=100 N pistonul mic se deplaseaza cu h1=10cm, iar pistonul mae se deplaseaza cu h2=1cm. Sa se afle a)L1,2=? B)F2=? C) S2 supra S1=?

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
