1.00 mole of an ideal monatomic gas is in a rigid container with a constant volume of 2.00 L. The gas is heated from 250.0 K to 297.0 K. Calculate the ∆S(gas) for this process, in J/K. Consider a gas cylinder containing 0.250 moles of an ideal gas in a volume of 6.00 L with a pressure of 1.00 atm. The cylinder is surrounded by a constant temperature bath at 292.0 K. With an external pressure of 3.00 atm, the cylinder is compressed to 2.00 L. Calculate the ∆S(gas) for this compression process, in J/K.

If a gas is compressed isothermally, which of the following statements is true? (a) Energy is transferred into the gas by heat. (b) No work is done on the gas. (c) The temperature of the gas increases. (d) The internal energy of the gas remains constant. (e) None of those statements is true.

A 1.00-mol sample of hydrogen gas is heated at constant pressure from 300 K to 420 K. Calculate (a) the energy transferred to the gas by heat, (b) the increase in its internal energy, and (c) the work done on the gas.

A sample of a monatomic ideal gas occupies 5.00 L at atmospheric pressure and 300 K (point A in Fig. P17.68). It is warmed at constant volume to 3.00 atm (point B). Then it is allowed to expand isothermally to 1.00 atm (point C) and at last compressed isobarically to its original state. (a) Find the number of moles in the sample. Find (b) the temperature at point B, (c) the temperature at point C, and (d) the volume at point C. (e) Now consider the processes A B, B C, and C A. Describe how to carry out each process experimentally. (f) Find Q, W, and Eint for each of the processes. (g) For the whole cycle A B C A, find Q, W, and Eint. Figure P17.68
