    Piston volume and pressure problem

    Thanks! For some reason I'm still not getting the answer: 400 J = - 101,300 pa (0.0006 m^3 - V_f) 400 = -61 + 101,300V_f V_f = 0.00455 m^3 = 4550 cm^3 "Once you get V_f, can you find the final temperature?" Yeah, this part should be easy. V_1 over T_1 = V_2 over T_2
