WebThe ideal gas law and the first law of thermodynamics apply to the gas. Q = ΔU + W, pV = nRT, and C v = C p − R. (a) This is an isothermal process for an ideal gas, so ΔU = 0 and Q = W Since the volume decreases (compression), W is negative and Q = −600 J. Since Q is negative, heat flows out of the gas. (b) W = pΔV = nRΔT. WebThe second law of thermodynamics is a statement of the general tendency of entropy to increase; that is, of the ordered state of a thermodynamic system to become more …
