Lesson 3: Surface Tension Flashcards
1
Q
Pulling force that acts parallel to the surface and is due to the attractive forces of the molecules of the liquid
A
surface tension
2
Q
Rise or fall of a liquid in a small-diameter tube inserted into the liquid
A
capillary effect
3
Q
how is strength of capillary effect quantified?
A
by the contact (or wetting) angle ϕ – angle that the tangent to the liquid surface makes with the solid surface at the point of contact
4
Q
what force explain capillary effect?
A
adhesive and cohesive forces
