WebThe work done by the gas in the expansion is dW = pdV;dQ = 0 d W = p d V; d Q = 0 because the cylinder is insulated; and the change in the internal energy of the gas is, from Equation 3.9, dEint = CV dT. d E int = C V d T. Therefore, from the first law, CV dT = 0−pdV = −pdV, C V d T = 0 − p d V = − p d V, so dT = −pdV CV. d T = − p d V C V.
