24.- Find the amount of heat absorbed by 5.0 mol of argon (assumed ideal) when expanding...
1.5 moles of an ideal gas, for which the molar heat capacity Cv.m = 3/2R, initially at 25.0°C and 1 atm undergoes a two-stage transformation. Calculate q. w. Au in kJ for the complete process (a+b). a. The gas is expanded isothermally and reversibly until the volume doubles b. Beginning at the end of the first stage, the temperature is raised to 100.0°C at constant volume. 9 -2.57 ki A. W = 2.57 kJ AU = 5.14 k) = +2.57...
4. An ideal gas of 5.0 mol CO2 is originally confined in 15 L at 300 K. Assume it undergoes isothermal expansion against a constant pressure of 1.0 atm until equilibrium is reached. Assume the heat capacity of CO2 at constant pressure, Cp.m is 37.11 J/mol K. Calculate the final volume, q, w,aU, and △H for the process. (15%) 5. Calculate the minimum work needed to freeze 250 g of water originally at 0°C standing in a room at 20°C....
