Question

explain the phenomenon of capillarity
within 50 words

Answer 1

CAPILLARITY:
when a capillary tube( tube of very fine bore) open at both ends is dipped into a liquid vertically the liquid inside the capillary tube Rises or Falls due to the surface tension this phenomenon is called as a capillary action this is also called as capillarity

a) : when a glass capillary tube is dipped into a liquid of angle of contact less than 90 ° then liquid Rises up in a tube till the equilibrium is attended here Adhesive forces are greater than Cohesive forces
eg: water and acetone etcc

b): when a glass capillary tube is dipped into a liquid of angle of contact greater than 90 ° the liquid gets description in the tube till the equilibrium is attinad here to forces are greater than Adhesive forces
eg: Mercury etccc
