Yes but, if the piston move, the temperature from compartments don't change ? I've found P1 & P2: P1= P0L/L-2h P2=P0L/L+2h Now, i must to found the force. F=P*S but what P i must multiply to S to found force ? I solve it ! F=(p2-p1)*S = 888N Thank you very much !

Yeah but can you explain me why p0v0=p1v1 ? Thanky you for response.

Homework Statement [/B] A horizontal cylinder with length L=1m and section S=2*10^(-3) is divided in two parts by a piston. In theese compartments is air at pressure p0=10^5N/m^2 and same temperature. The piston move with h=0,4m from initial position. Which is force to hold piston in this...

//Sorry for x2 post.

Because F = -G ? Or.. F is a little bit stronger that G to lift ?
