7. A cylinder with a moving piston expands from an initial volume of 0.250 L against anexternal pressure of 2.00 atm. The expansion does 288 J of work on the surroundings. What is thefinal volume of the cylinder?A. 3.77 LB. 1.23 LC. 1.67 LD. 0.739 L

w = -P ΔV = -P (V2 - V1) -w / P = V2 - V1 (-w/P) + V1 = V2 Therefore the final volume of the…
