Surface tension, capillary action, applicationsSurface tension is the property of a liquid's surface to resist external forces and minimize its surface area.It is caused by the cohesive forces between liquid molecules, which are stronger at the…
Viscosity, Stokes’ law, terminal velocityViscosity is a measure of a fluid's resistance to flow, caused by internal friction between fluid layers.Fluids with higher viscosity flow more slowly, while those with lower viscosity flow more…
