ytspänningen
Ytspänningen is a phenomenon observed in liquids, referring to the tendency of liquid surfaces to shrink into the minimum surface area possible. It is a consequence of the cohesive forces between liquid molecules. At the surface of a liquid, molecules are pulled inwards and sideways by neighboring molecules, but not outwards, as there are no molecules above them. This imbalance of forces creates a net inward pull, which causes the surface to behave like a stretched elastic membrane.
This surface tension is responsible for several everyday occurrences. For example, it allows small insects to
The magnitude of surface tension varies between different liquids and is affected by temperature and the presence
