Review the following statements regarding properties of real and ideal gases. Identify the statement that is not correct? Group of answer choices The ratio PV/RT = 1 for one mole of an ideal gas. The ratio PV/nRT < 1 for one mole of a real gas because of repulsive interactions between the molecules. The ratio PV/nRT > 1 for one mole of a real gas because of the finite size of the molecules. At low temperatures, the attractive forces between molecules cause a real gas to deviate from ideal gas behavior. At high pressures, the finite size of the molecules causes a real gas to deviate from ideal gas behavior

.The ratio PV/nRT < 1 for one mole of a real gas because of repulsive interactions between the molecules.

Explanation:

The expression PV/nRT is referred to as the compressibility factor commonly designated as Z.

This compressibility factor (Z) for real gas is often less than 1. Z<1 means attraction forces are dominant in the system.

Hence, Z<1 implies attractive and not repulsive force dominance in the system.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
