If a piston performs 64.8 J of work and exerts an external pressure of 87.5 N/m², what is the change in volume of the cylinder?

Question

Quizplus · Accepted Answer

The work performed by the piston is given as:
$W=P\Delta V$
Where, $W$ = work done = 64.8 J
$P$ = pressure = 87.5 N/m$^2$
$\Delta V$ = change in volume of cylinder (unknown)
Therefore, 
$\Delta V = \frac{W}{P} = \frac{64.8}{87.5} = 0.741$ m$^3$ (rounded to three significant figures)
