From the figure, their centres are separated by 2r at the point of contact
Volume of 1 molecule = 4/3 πr³ = V_mol
Effective volume = 4/3 π(2r)³ = 8 4/3πr³ = 8V_mol
Excluded volume per molecule = ½ 4/3 π(2r)³ = ½ 8 4/3πr³ = 4V_mol
Greater the excluded volume, greater the deviation from ideal behaviour.

Explanation:

Collision of Gaseous Molecules:
When two gaseous molecules of equal radius r collide, their centres are separated by 2r at the point of contact. This means that the distance between the two molecules is equal to the sum of their radii.

Effective Volume:
The effective volume occupied by two molecules is eight times the volume of each molecule. This is because the volume of each molecule is πr^3, and when two molecules come together, the total volume they occupy is 8(πr^3).

Excluded Volume:
The excluded volume is four times the volume of each molecule. This means that the volume that cannot be occupied by the two molecules due to their physical size is four times the volume of each molecule.

Deviation from Ideal Behavior:
Greater the excluded volume, greater the deviation from ideal behavior. This is because in ideal gas behavior, molecules are assumed to have zero volume and no intermolecular forces. When the excluded volume is significant, it indicates that the molecules have a finite size and interact with each other, leading to deviations from ideal behavior.

Attempt All sub parts from each question.Molecular Perspective In water, there are two types of molecules. Some molecules are at the surface, called exterior molecules, and some molecules are inside, called interior molecules. The interior molecules are attracted to all the molecules around them. The exterior molecules are attracted to only the other surface molecules and to those below the surface. So that the energy state of the molecules on the interior is much lower than that of the molecules on the exterior. The molecules always try to maintain a lower energy state and hence the exterior molecules experience a downward force. This force is known as cohesive force. As a result they try to maintain a minimum surface area, thus allowing more molecules to have a lower energy state. Thus surface tension is created. The water molecules attract one another due to the water molecule’s polar property. The hydrogen ends, which are positive in comparison to the negative ends of the oxygen, cause water to "stick " together. This is why there is surface tension. Water has very high surface tension. It is 72.8 milli newton per meter at 20°C.Q. The energy state of the interior molecules of a fluid is
