Answer:
Surface tension is defined as the force acting across the surface per unit of surface length perpendicular to the force. its unit is Newton per meter (N/m). Viscosity is the internal friction in a fluid. Viscous forces opposes the motion of one portion of a fluid relative to the other. Its unit is pascal second(Pa-s).
