Question

what is surface tension ?how it calculate ​

Answer 1

Answer:

• Surface tension is defined as the ratio of the surface force F applied on a liquid to the length d along which the force acts. It is responsible for insects to walk on water, or a paperclip to "float".

• The equation is given by:
• →Surface tension = (surface force)/(length force acts)

Answer 2

Answer:

surface tension is the tendency of fluid surfaces to shrink into the minimum surface area possible.

formula: F (upward) = T2πr
