If gas in a cylinder is maintained at a constant temperature T, the pressure P is related to the volume V by a formula of the form
P = (nRT/(V - nb)) - ((an^2)/V^2)
in which a, b, n, and R are constants. Find dP/dV
I tried to solve it by knowing that a, b, n, and R are constants, so only V, T are variables.
So I did this:
P = nR(dT/d(V-nb)) - ((an^2)*(-2V^-3))
but I still didn't get the correct answer. I believe I did something wrong, could someone help me out?
