atm is allowed to expand to 13.0 L. The tem-
perature remains constant. What is the ¯nal
pressure?

PV = nRT.
n and T don't change, so pressure x volume remains the same.
You can see that the volume doubles. What has to happen to the pressure?

you ought to probable techniques to do those on your individual... a million) P1V1 = P2V2 (.seventy six)(6.5) = (13)P rigidity = .38 2) sixty one.3mL = .0613L 68C = sixty 8+273 ok = 341 ok 128C = 128 + 273K = 401K V1/T1 = V2/T2 (.0613)/(341) = V2/(401) quantity = .072L 3)decrease 4) V1/ T1 = V2 / T2 (21) / (298) = (fifty six.a million) / T2 temperature = 801K 5) shrink in 0.5
