Surface tension is the tendency of liquid surfaces to shrink into the minimum surface area possible. The tension of surface allows insects (e.g. water striders), usually denser than water, to float and slide on a water surface. However, It is nothing but the force act on one surface or one side. For instance, the atmospheric pressure act on the water in an open vessel.

• Surface tension = Force/ side or page
• Surface tension = Newton/ meter
• Newton = kgm/s²

However, In dimensional unit,

Dimension of surface tension

• Surface tension= (kgm/s²)/m=kgm/(s²)×m
• Surface tension = kg/s²= MT⁻²
