Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

Initial state the pressure and volume are

P = 1 bar

V = 1 litre

Now the process equation is given as

PV = constant

So now the pressure is increased to

P = 4 bar

so volume must decrease by 4 times

so final volume is

V = 0.25 litre

Now the pressure is constant and volume again increased to V = 1 litre

Now in final step the volume will become constant and again pressure will become P = 1 bar

so this is a cyclic process and figure is attached at following

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
