Given a certain liquid with vaporization enthalpy (vaphθ) of 260 kJ mol⁻¹, calculate q, w, h, and u when 0.5 mol is vaporized at 250K and 750 torr.
(a) q = 130 kJ, w = -130 kJ, h = 130 kJ, u = 390 kJ
(b) q = -130 kJ, w = 130 kJ, h = 130 kJ, u = 390 kJ
(c) q = -130 kJ, w = -130 kJ, h = 130 kJ, u = 390 kJ
(d) q = 130 kJ, w = 130 kJ, h = 130 kJ, u = 390 kJ
