HOMEWORK CHAPTER 6 KEY 24. Calculate the internal energy change for each of the following. a. One hundred (100.) joules of work are required to compress a gas. At the same time, the gas releases 23 J of heat. b. A piston is compressed from a volume of 8.30 L to 2.80 L against a constant pressure of 1.90 atm. In the process, there is a heat gain by the system of 350. J. c. A piston expands against 1.00 atm of pressure from 11.2 L to 29.1 L. In the process, 1037 J of heat is absorbed.

30. One mole of H 2 O (g) at 1.00 atm and 100. o C occupies a volume of 30.6 L. When one mole of H 2 O (g) is condensed to one mole of H 2 O (l) at 1.00 atm and 100. o C, 40.66 kJ of heat is released. If the density of H 2 O (l) at this temperature and pressure is 0.996 g/cm 3 , calculate Δ E for the condensation of one mole of water at 1.00 atm and 100. o C.
36. Consider the following reaction: 2 H 2 (g) + O 2 (g) 2 H 2 O (l) Δ H = -572 kJ a. How much heat is evolved for the production of 1.00 mol of H 2 O (l)
