What is Surface Tension?
Learn how molecules at the liquid’s surface are pulled inward by cohesive forces, causing the surface to behave like a stretched elastic membrane

Units and Formula:
Explore how surface tension is quantified—expressed as force per unit length (N/m) or energy per unit area (J/m²)—and see the basic equations:


Real‑World Examples:
From water striders walking atop ponds, to droplets hanging off faucets, and even soap bubbles—surface tension shapes the behavior of liquids in many visible ways

Simply Explained:
For a more intuitive take, here’s how a Redditor described it:

“Surface tension is basically the tendency of molecules of a liquid to attract one another. … surface tension will cause the surface of the liquid to contract into a sphere.”
