A liquid does not wet the sides of a solid, if the angle of contact is
Text Solution
Verified by ExpertsThe correct answer is:
B
We know that the liquids make the solid substances wet when they get into physical contact
with each other. This depends on the contact angle between the liquid and solid surfaces. When the liquid does not wet the sides of a solid object, it means that the angle of contact is more than 
but less than 
.
A liquid does not wet the solid surface if the angle of contact is obtuse (i.e. 
).
