Water molecules attract each other like tiny magnets, which leads to the cohesive forces that hold them together. Adhesion, on the other hand, occurs when molecules cling to other substances, like water and glass forming a meniscus. Together, cohesion and adhesion shape water’s unique behavior on various surfaces. 00:00 Intro 00:17 What is Cohesion? 02:07 What is Adhesion? 03:00 What is a meniscus? 03:56 How fog nets collect water from air 04:38 Summary Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.
