a) True, cohesive forces are intermolecular forces between like molecules and adhesive forces between unlike molecules.
b) True, only due to cohesive force, all the molecules of droplets(which are like molecule) are attracted towards each other to form drop
c) True, if the cohesive force becomes weak as to adhesive forces, then there will be no force to bind water molecules and the drop will collapse and spread into film.
d) True, It's only due to cohesive force that mercury doesn’t wet the glass.

The first option is clearly the theory which you are gonna use in the other three. If cohesive forces are stronger than adhesive then the drop will have strong binding energy. This can be used to explain option (B). The contrary is itself the next option (C). Option (D) is the example for the above theory.

Select the correct statement(s).a)Cohesive forces are the intermolecul...

Explanation:

Intermolecular Forces:
- Cohesive forces are the intermolecular forces between like molecules, such as hydrogen bonding, Van der Waals forces, etc.
- Adhesive forces, on the other hand, are the intermolecular forces between unlike molecules.

Behavior of a Drop:
- A drop will maintain its shape if cohesive forces are stronger than adhesive forces.
- If the cohesive forces are weak compared to adhesive forces, the drop will collapse and spread into a film.

Mercury's Cohesive Forces:
- In the case of mercury, the cohesive forces are strong due to metallic bonds between atoms.
- Mercury does not wet glass because its cohesive forces are stronger than its adhesive forces.

Therefore, all the statements (a), (b), (c), and (d) are correct in explaining the relationship between cohesive and adhesive forces, as well as their effects on the behavior of drops.

Similar Class 11 Doubts

Alkanes are almost non-polar molecules because of the covalent nature of C—C and C—H bonds and due to very little difference of electronegativity between carbon and hydrogen atoms. They possess weak Van Der Waals forces. Due to the weak forces, the first four members C1 to C4 are gases, C5 to C17 are liquids and those containing 18 carbon atoms or more are solids at 298K. They are colourless and odourless. In alkanes, there is a steady increase in boiling point with the increase in molecular mass. This is due to the fact that the intermolecular Van Der Waals forces increase with increase of the molecular size or the surface area of the molecule. With the increase in branching, the boiling point of alkanes decreases. The given questions (i) to (iv) consist of an assertion (

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 water molecules attract one another due to the water molecule’s
