Why does water on a clean glass surface tend to spread out while mercury on the same surface tends to form drops, also known as wetting behavior?
Options
- ABecause water molecules have stronger cohesive forces than adhesive forces with the glass surface.
- BDue to the higher density of mercury compared to water.
- CIt is a result of the temperature difference between water and mercury.
- DBoth water and mercury have similar adhesive forces with the glass surface.
Correct answer
A. Because water molecules have stronger cohesive forces than adhesive forces with the glass surface.
Step-by-step solution
Correct Option is : (A)
Because water molecules have stronger cohesive forces than adhesive forces with the glass surface.
Because water molecules have stronger cohesive forces than adhesive forces with the glass surface.
