Surface Tension
Surface tension is the property of a liquid that allows it to resist an external force due to the cohesive nature of its molecules. In space and astronautical engineering, surface tension plays a crucial role in the behavior of fluids in microgravity environments. In the absence of gravity, fluids tend to form spherical shapes due to the balance between surface tension and internal pressure. This behavior is exploited in the design of fluid management systems in spacecraft, where surface tension is used to control the flow and distribution of fluids. Surface tension also affects the behavior of bubbles and droplets in microgravity, which can have implications for experiments and processes involving fluids in space.
