7.14 Indicate whether each of the following statements about a process in a closed system with a constant volume is always true, always false, or true in certain conditions (specify the conditions): (a) AU = 0; (b) w = 0; (c) w 0; (d) AU = q; (e) AU = w. 7.28 Calculate the heat that must be supplied to 0.104 g of Ne(g) at 0.250 atm to raise its temperature from 22.0C to 60.0C at (a) constant pressure and (b) constant volume. Assume that neon behaves as an ideal gas. 7.48 Calculate the heat generated by a reaction mixture of 13.4 L of sulfur dioxide at 1.00 atm and 273 K and 15.0 g of oxygen in the reaction 2 SO(g) + O(g) 2SO3(g) AH = -198 kJ
