Two moles of oxygen gas, which can be regarded as ideal with ?? = 29.4 J/(K ∙ mol) (independent of temperature), are initially at 298 K in a volume of 12.5 dm3 . The gas is expanded reversibly to 353 K at constant pressure. Calculate the final volume and q, w, ∆U, ∆H, ∆S. (25 points) 4. Suppose that the gas in question 3 is reversibly compressed to half its volume at constant temperature (298 K). Calculate the final pressure...
One mole of oxygen gas (T=273K), which can be regarded as ideal gas, is compressed reversible to half its volume at constant pressure, how much work is done on the system?
Three moles of an ideal gas are taken around the cycle abc shown in the figure (Figure 1) . For this gas, Cp=29.1 J/(mol?K). Process ac is at constant pressure, process ba is at constant volume, and process cb is adiabatic. The temperatures of the gas in states a, c, and b are Ta=300K, Tc= 492 K, and Tb= 600 K. Calculate the total work W for the cycle
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...
6. The formula dS = dQ/T makes it look like a system can only increase its entropy by absorbing heat. You must however remember that this equation is only true for reversible processes. Entropy can change for a system without absorbing any heat. Consider the following scenario. You are given an insulated container with two compartments. The whole container is at the temperature T which remains constant. One compartment has a volume V1 and has n1 moles of an ideal...
