question 33

• A)At low temperatures,the attractive forces between molecules cause a real gas to deviate from ideal gas behavior,and the van der Waals a factor adjusts for this.

• C)The ratio PV/RT = 1 for one mole of an ideal gas.
• D)The ratio PV/nRT < 1 because of repulsive interactions between the molecules.
• E)The ratio PV/nRT > 1 because of the finite size of the molecules.
