Answer:
Viscosity is a measure of a fluid's resistance to flow. It describes the internal friction of a moving fluid. A fluidwith large viscosity resists motion because its molecular makeup gives it a lot of internal friction.
Surface tension is the tendency of liquid surfaces to shrink into the minimum surface area possible. Surface tension allows insects, to float and slide on a water surface without becoming even partly submerged.
SI unit: Newton per metre.

A liquid's resistance to being deformed or moved. This is caused by the friction between molecules. Compared to viscosity, surface tension is a simpler phenomenon. It is basically stable, changed mostly by temperature and chemicals that modify the bonding characteristics of the molecules.
