Hi there.
00:03
This question can be answered based upon the definitions of cohesion and adhesion.
00:12
Cohesion is when atoms or molecules stick to themselves.
00:38
So this can be through intermolecular forces or forces between the atoms or molecules.
00:45
So for example, water molecules attracting to other water molecules to form water droplets or surface tension.
00:53
Mercury attaching to itself to form beads of mercury.
00:59
That is cohesion when a substance is attracted to itself.
01:04
Adhesion is when the substance is attracted to particles of another substance.
01:27
And cohesion and adhesion have all to do, have everything to do with how strongly particles are attracted, attracted either to themselves or to something else.
01:40
So in the case of water, water beads up due to cohesion.
01:57
In that instance, water is more attracted to itself than it is to the other substance...
