Surface tension
Surface tension is the elastic tendency of a fluid surface which makes it acquire the least surface area possible. It is defined as the ratio of the surface force F applied on a liquid to the length d along which the force acts. An increase in temperature lowers the net force of attraction among molecules and hence decreases surface tension.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)
The equation is
γ = F /d
We have:
γ: Surface tension
F: Force applied on the liquid
d: length where the force acts
