Which of the following properties minimize the differences between an ideal gas and a real gas?

Question

Low pressure, high temperature, low dipole moments, high density, and/or strong intermolecular forces?

Thanks in advance for the help.

Answer 1

Deviations from ideal gas behavior occur because of intermolecular (Van der Waals) attractions. We expect that these attractive forces will increase when:
-There is high density, because more molecules of gas are compacted into a small volume, increasing intermolecular contact and VDW forces.
-There is high pressure. High pressure causes gases to come into closer contact with each other (they are "pushed" into contact)
-High intermolecular forces will clearly cause greater deviation from ideal gas behavior.

On the other hand:
-Low dipole moments cause molecules to NOT have high intermolecular attractions, and so we expect that low dipole gases have greater ideal gas behavior

-Low pressure likewise causes molecules to expand to a higher volume (by the law PV=constant, at a given Temperature). Higher volume means less intermolecular contact.

-High temperature decreases intermolecular contact because molecules have higher Kinetic Energy and have less contact time.

Answer 2

properly to respond to this question you choose the perception made for an perfect gasoline: that the atoms soak up no area and that there are no intermolecular interactions. A .of course is going against those assumptions. B. Dipole moments are with reference to the polarity of the molecules the decrease the dipole 2d the less polar the molecule and hence the weaker the intermolecular interactions. So this is one. C. intense density potential that the molecules will soak up an significant share of the vessel they are in so this isn't any longer one. D. Low rigidity is the choice of C so via a similar argument that's one. E. intense temperature potential that the capability of intermolecular forces would be much less whilst in comparison with the possibility of the molecules, thereby having much less effect so this is one. In precis B D and E are the spectacular solutions.

Answer 3

Anythin which reduces the intermolecular attraction would jus contribute to minimize the diffrance.
So the first 3 will minimize while the last 2 will widen the gap.
best o luck.
