Can you use the ideal gas equation of state to determine the specific volume of Oxygen at 10 GPa and 500 K? I have been trying to figure why I would or would not be able to.

Answer #1

DEAR STUDENT, AS YOU RECALL AT HIGH PRESSURE GASES TEND TO DEVIATE FROM IDEAL BEHAVIOUR.. 10GPA IS VERY HIGH PRESSURE i.e. CORRESPONDING TO APPROX 9870ATM. THUS OXYGEN SHALL NOT BEHAVE AS IDEAL GAS AT SUCH A HIGH PRESSURE EVEN THOUGH TEMPERATURE IS HIGH (500K). THEREFORE, IF YOU ARE SOLVING A PROBLEM, IN MY OPINION USE IDEAL GAS EQUATION IF QUESTION PERMITS YOU TO USE IDEAL GAS EQUATION.

    The state of an ideal gas can be represented by a point on a PV (pressure-volume) diagram. If you know the quantity of gas, n, a unique point in pressure (P) and volume (V) can be used to determine a temperature (T). Each point on a PV diagram also has a single internal energy (U) assigned to it. If a process starts at a point and returns to that same point on a PV diagram, it returns to the same...

    Determine the Boyle temperature in terms of constants for the equation of state: PVm = RT{1 + 8/57(P/Pc)(Tc/T)[1 – 4(Tc/T^2) ]} R, Pc, and Tc are constants. Can someone please explain why I have to set [1 – 4(Tc/T^2) ]}=0 (I know that at Boyle's temperature B=0 since p->0 and the real gas will act as an ideal gas, but why is this specific part of the equation set to 0? thank youuu!!!
