Water does not wet an oily glass because
- A Cohesive force of oil is greater than adhesive force between oil and glass
- B Cohesive force of oil is greater than cohesive force of water
- C Oil repels water
- D Cohesive force of water is greater than adhesive force between water and oil molecules
Answer & Solution
Correct Answer
(D) Cohesive force of water is greater than adhesive force between water and oil molecules
Step-by-step Solution
Detailed explanation
The force of attraction between the same molecules is cohesive force and the force of attraction between different molecules is known as adhesive force. Since water bubble forms an obtuse angle with an oily surface, thus we can say that water-water molecules has strong…
