Question

when water spreads on a glass plate the force between its molecules and class molecules are due to a) surface tension
b)cohesion
c)adhesion
d)capilary attraction

Answer 1

adhesion. It's the force of attraction between a liquid & a solid surface.

Answer 2

adhesive force dear.

Answer 3

When water is poured on clean glass, it tends to spread, forming a thin, uniform film over the glasses surface. This is because the adhesive forces between water and glass are strong enough to pull the water molecules out of their spherical formation and hold them against the surface of the glass, thus avoiding the repulsion between like molecules.
