Question

Question 1 (1 point) 1.50 Oxygen PV 1.ok Ideal gas 0.0 0 200 400 600 800 1000 Pressure (atm) 1. Above is a graph of one mole oxygen and an "ideal gas". The ratio of PV/T is plotted as a function of gas pressure. Why is the line that represents oxygen different from that of the "ideal gas"? Oxygen deviates from an ideal gas because it is diatomic Real gas molecules have a small but measurable intermolecular attraction Oxygen is an abnormal gas because it is biologically active None of the above As the pressure of oxygen is increased, the volume of each individual oxygen atom becomes smaller

Answer 1

0.5 200 400 600 800 1000 The line that represents oxygen cliffe of the ideal gast as - 3 Real gas molecules have a small but measurable intermolecules attraction .

As pressure increases and volume decreases the volume of the gas molecules becomes significent in relationship to the Container vallime. In an extreme example, the volume com decreone below the molecules volume, thens (PY/RT) will be higher than ideal (vis higher) Deration from ideality does not depend on molecularfity or biological activity. & As the pressure of oxygen is increased, the volume of each individual of atom does not weconen.
