Explanation / Answer

9) B)2.41*10^5 pa

given,

Po = 1.013*10^5 pa

Area of the piston, A = 5*10^-4 m^2

weight, w = 70 N

Let P is the pressure of the gas.

as the piston is in equilibrium, net force actin on the piston must be zero.

Fnety = 0

P*A - Po*A - W = 0

PA = Po*A + W

P = PO + W/A

= 1.013*10^5 + 70/(5*10^-4)

= 2.413*10^5 pa
