Discover how cohesion between water molecules forms surface tension, enabling denser objects, like a needle, to sit on its surface. Investigate practical applications in clinical tests, camping, and hand washing. Explore adhesion, the pull of water molecules to other materials, and its contribution to capillary action. video https://cdn.kastatic.org/googleusercontent/9lyCeX9FfIsE-CssN_KAlVDiDd-7aVbwmzMd1aTJHPqd-ydjcYs6e65r0IVzvFjov5VUcExCiQK1_9dS3-kdwa4D Surface Tension and Adhesion Unravel the enigma of surface tension and adhesion in liquids, particularly water.
