What do we mean by cutting the surface with finger? (See below)

Answer»

The explanation of whole activity is given below

The meaning of cutting the surface with a finger is :

  • No, it isn't possible to break a stream of water with fingers.
  • The reason for this is that water is a liquid and its atoms are bonded together by attractive forces. 
  • Although the intermolecular attraction forces in water (liquids) are a bit lesser than solids so the molecules can move around freely, but these forces are strong enough to bind the water molecules with a considerable force so that they don't break.
